If you want to stay

and hit that bell. Please enjoy the video. So when you start
this, you just want to have your face in the water
with your scuba regulator in. Then the trick is to just
breathe in slowly and deeply. Try to breathe in like you're
breathing through a straw. And when you
breathe out, imagine you have a spoon of
hot soup that you're trying to blow cold. It's quite easy, right? Just breathe in and breathe out. Again, breathe in
and breathe out. Just listen to the sound
of your scuba bubbles. Just remember that when
you breathe in and out to breathe in through your
mouth and not through your nose. Right, so when you breathe
in and out a few times comfortably, you
can lift your head from the water, and great job. Start the skin dive
by having your mask on and your snorkel in your mouth. Take a couple of really
nice deep breaths. And once you're ready,
take a final deep breath and swim slowly down
towards the bottom. Swim under the water
for a few meters, and then when you
reach the surface, clear your snorkel
using the blast method. Keep your mask and
snorkel in your mouth. For the dive
equipment setup, start by inspecting the scuba tank
and check all the numbers on the tank. Especially check the
hydrostatic test date and check your official
inspection, making sure that all the dates are correct. Check with the
O-ring is in there and that it is in
great condition. Then check the tank valve,
which way is open and close, and give it a little
burst to clean the valve. Once that's OK, grab your
BCD at the BCD handle, put your safety strap away,
and then correctly place the BCD over your scuba tank. Make sure that it's at least
four fingers from the top, and then close the buckle. Double check if
everything is attached. Make sure that the tank valve
is parallel with the BCD handle. Place on the safety strap
and tighten the safety strap accordingly. Again, double check
your BCD handle, that it's parallel
to your tank valve. You can also check
if the tank is not too high or too low
by placing your hand and fingers at the top of
your valve and your BCD. Now, to make sure
that everything is attached correctly,
grab your BCD tank or the handle of your
BCD and then give it a little wiggle. Just make sure you be
careful of your back. Grab your regulator. Unscrew the dust cap
from the first stage. Make sure that the
two briefing hoses are on the right side of the
right shoulder of your BCD. Place the first
stage over the valve, and then gently
screw until it's ed. Now, it's very important,
do not do this too tight. So only three-finger tight. It's all OK if your first
stage moves a little bit before we open up the tank. Then attach the
low-pressure inflator hose by pulling back the top off
your low-pressure inflator hose and connecting it to the
inflator hose of the BCD. Make sure afterwards
you streamline it. Once it's all streamlined
and looks in order, grab your alternate air source,
and attach your alternate air source at the right
spot of your BCD. Make sure the yellow
is shining outwards. Now, if everything looks good,
before we open up the tank, turn your SPG away from you so
the glass in the unlikely event if it damages, it
cannot hurt anybody. Hold down the inflator
button of the BCD, and then slowly
open up the tank, instantly releasing the
inflator button of the BCD. All the way open up
the tank until the end. Now, do a full check
of your dive equipment by fully inflating the BCD first
until air escapes from the BCD. And then wait a second. Make sure there's no leaks. Squeeze it a little bit. So now we check that
air actually goes in and that there's no leaks. Then deflate the BCD by
releasing all the air. Then check if it also works
orally by putting a bit of air in there. A couple of breaths is enough. Make sure you press
down the deflator button when you breathe in. Once that's all OK, then
deflate the BCD again. Then grab your second
stage in your right hand and your SPG in your left hand. Clean your second stage
by purging a little bit, then smelling it, making
sure that the air is not contaminated. And then put your second
stage in your mouth and breathe in slowly and
deeply a few times while looking at your air gauge. Your air gauge needle
should stay still. If it moves, then
there is a problem. If it is all OK, then put
your second stage down again, take out your alternate air
source, and repeat the process. Gently breathe in
and out, making sure that everything is OK. Replace the alternate
air source and make sure that everything is
streamlined again. Then after it's all
good and streamlined, gently place your
equipment on its side. Make a nice little package out
of it as compact as possible. Now, when it all looks good
and done, you can walk away. Start by closing off your
scuba tank completely. Turn off the air all the way. Once it's turned off, take
out your alternate air source. Hold it with your
right hand, and then your second stage
in your left hand. Purge at exactly the same
time both second stages till all the air is
released from the hoses and the first stage. Gently put it on the floor. Un-streamline your LPI
hose and disconnect it by pulling back to top of the
LPI and gently disconnect it. Then gently unscrew your first
stage from the tank valve. And then very
important, remember to dry that dust
cap from any water, so no water can enter
your first stage. We recommend using a dry
cloth or towel for this one. Once it's OK, place back the
dust cap on the first stage. Double check everything
for any leaks. And once that's OK, you can use
what we call a spaghetti loop technique to make a
nice little loop out of your regulator
system, and then gently put it on the floor. Release your safety strap. Take it off the tank valve. Then hold onto the
BCD with one hand. Release the tank strap,
and remove the BCD from the tank cylinder. Gently put it on the floor again
and make a nice little package out of it. Then grab the tank
very gently, put it on its side on the floor, so
it can't fall over anymore. Put your BCD and the
regulator together. Double check if
everything is streamlined. And then you can walk away. First thing you do is
with your right hand, hold down the deflator
button continuously. Then with your left hand,
squeeze in the LPI hose to the top, and with your
pointer finger and thumb, pull back the top of your
LPI hose and disconnect it. Then gently put it back on,
and make sure everything is streamlined. First you recognize that there
is a problem with your buddy's cylinder tank strap. Clearly communicate
to your buddy that something is wrong
with the connection of his scuba
cylinder tank strap, and that you will reconnect it. Ask your buddy to
wait patiently. Then swing behind your buddy. Turn the tank, readjust. Make sure that the tank
valve is parallel to the BCD and that there is at least
four fingers from the top. You can use your knee
to easily readjust your tank when effort's needed. When it's OK, reconnect
the cylinder strap. Double check if
everything is straight, everything is streamlined, and
that the connection is steady. Once everything is
perfectly back into place, communicate with your buddy
that everything is OK, buddy up, and
continue your dive. The first thing that you do
is to fully inflate your BCD. Then lay on your back and
open up your weight belt. Then under the water behind
your back, take it off. Remember not to drop it. Keep it close to your body
so you keep your balance. Then make sure that
the weight belt is not twisted or anything,
and then put it back. Make sure that you
give the buckle to your left hand and the open
hand is in your right hand. Keep laying on your back and
reconnect the weight belt. Make sure that the SPG is not
in between the weight belt. Double check if all the weights
are OK, evenly displaced, and nothing is entangled. Start by deflating your BCD. And while you're
deflating your BCD, effectively kick so your
face stays above the water. Then with your right hand,
take off your weight belt and drop it right next to you. Then while you're now
positively buoyant, lean backwards to end the skill. First thing you do is your
body picks up the equipment. Be very careful about your back. Hold it in one hand
at the tank valve and in the other
hand under the tank. Put the tank on your knee,
then the other person first puts your right arm in it. Then your left arm. Bend forward a little bit. Close the Velcro. Close the buckle on
the belly and pull down the shoulder straps. Remember to close the
chest strap as well. Once you're OK, tell
your body that you're OK, and he can gently let go. Be even more careful
with your back right now, because you have
a tank on your back. Pull up your buddy's tank. And then the same way as
you got into the tank, your buddy can now go
into the tank as well. Again, make sure that
everything looks good, and it's streamlined. And now we're ready to
start the buddy check. So remember the
buddy check BWRAF. The first thing you
do, the B, is from BCD. So inflate each other's BCDs and
check that nothing is leaking. Then deflate each other's BCDs. Once both BCDs
are deflated, then orally inflate
each other's BCDs, making sure that it all works. Three breaths should be enough. Then deflate each other's BCDs. And then we have to
W from Weight belt. Check your buddy's
weight belt. Make sure it's a right hand release,
that all the weights are evenly-distributed and nothing
is twisted or entangled. And vise versa, your buddy
will also do that with you. If you have integrated
weights, then check if the integrated
weights are there. Then the R from Releases. So check if all the
releases are connected and everything is snug. Make sure it's comfortable--
not too tight, but of course definitely not too loose. Especially your tank strap--
it's really important that that is connected the right way. Then your buddy does
it in your equipment. Then we go to the A from Air. Now, before you take
your second stage, first check on your buddy if
the tank is completely open. Make sure you look on the
valve and check the arrows. Then you open it the right way. Once you've checked
on each other that the tank is
properly opened, then grab your air gauge,
hold it in your right hand, and then with your left
hand, take the second stage off your body. First, we want to
clean it by purging it. Then gently purge
it to smell the air. And then breathe from it. Take three slow, deep
breaths in and out, and check each other's
air gauge, making sure that the needle doesn't move. If that is all
OK, then you check your buddy's
alternate air source using the same procedure. Make sure that when
you put it back that you streamline
everything correctly. And make sure the yellow
is really facing out. Then your body does it on you. And again, always double
check if your buddy does the buddy check correctly. Once it's all
streamlined, you want to do the F for the Final OK. Now, the F means that we want
to double check everything. So make sure that all the
hoses are connected correctly, nothing is entangled, alternate
air source is under the arm, everything is streamlined. And correct any
problems that you occur. Make sure that we
have a mask, snorkel. Streamline the SPG. Make sure we have our fins. Now, then a final OK, and
we're ready to go scuba diving. Make sure that you
have your mask on and your snorkel in your mouth. Then fully inflate your BCD
by pressing the inflator button until air
releases from your BCD. Lean backwards and make
sure that you're completely positively buoyant. Once everything is
OK, stand back up. Make sure you're
completely vertical. Stretch that deflator
hose as high as you can. Fully deflate your BCD. Use your right hand to
squeeze the last remaining air out of your BCD and
simulate that you're going down. First, take a nice deep
breath in and then take your second stage out. Make sure your mouth piece
is down and you blow bubbles. Then put your second
stage back into your mouth and clear it by blasting
through it forcefully. Then resume breathing. The second way is to take
out your second stage, again mouthpiece down,
blow bubbles, put it back into your mouth, and then
gently press the purge button to release all the water
from the second stage. And then resume breathing. Start by taking a
nice deep breath in. Take out your second
stage, mouthpiece down. Remember to blow bubbles. Move to the right and drop it. Stretch your right hand,
touch your knee, bottom tank. Move it around like in a sweep,
then grab your second stage. Make sure that it's
the right way up. Put it back into your mouth
and clear it either way you like it. Then resume breathing. Start by putting a
little bit of water into your mask just
on the eye level. Then with two fingers, touch
the top frame of your mask. Breathe in through
your mouth and gently out through your nose
while looking up. And then all the water is
cleared from your mask. First thing that you do is to
make contact with your body. Then clearly signal that you're
out of air and that you want the alternate air source. Your buddy now takes
the alternate air source and makes sure that the
hose is above the arm. You switch from
your second stage to your altered air source,
making sure you blow bubbles in between. Clear the alternate air
source either way you like it. Then create a Roman arm shake
so you stay close together. Signal OK, and you're
ready to go up. And then grab the deflator hose. Deflate your BCD continuously,
while simulating that you're going up to the surface. Remember to look at each other. When you look up to the surface,
everything is clear above you. And keep deflating your
BCD, breathing slowly in and out from your
alternate air source. You're going to be doing
this for 30 seconds in total. Just keep breathing. Once the 30 seconds are
finished, then before you take out your
alternate air source, recover your primary
second stage. Switch between. Make sure again your blow
bubbles in between switching. Give the alternate air
source back to your buddy and help your body to
reattach it and streamline it. And that's the end of the skill. Start by being in perfect trim. Don't touch the
bottom or the surface. Make sure that you're
completely streamlined and have a little bit
of air in your BCD, adjusting it for
neutral buoyancy. Swim slowly forward
towards the deep end. And once you're ready to
descend from the shallow to the deep end,
make sure that you equalize your ears with
the Valsalva maneuver or any other technique. Release some air from the BCD. Slowly exhale so
you are descending, equalizing all the way down. Make sure that you don't touch
the bottom of the deep end, and continue your
dive in the deep end. Make sure that your
equipment is streamlined. Have your hands in front
of you to make sure that you're streamlined
with your hands, that you're in perfect
trim horizontal, and then you can use any
finning technique you'd like. We recommend the scissor kick,
or even better, the frog kick. Double check once in a while
if you're still streamlined, and adjust your
buoyancy accordingly. Keep swimming around. Again, it's important
not to touch the bottom or the surface. And every now and
then, double check yourself that you're
still streamlined and everything is in order. Gently swim. Slowly is the key. Make sure you look around,
you don't touch anything. Keep swimming from the
shallow towards the deep end. Again, adjust some buoyancy
when effort's needed. Remember again that once you
go from the shadow to the deep, that you equalize your
ears on the way down. You can choose any
technique you like-- Valsalva maneuver,
swallowing, wiggling your jaw, whatever you prefer. Also it helps releasing some air
from your BCD on the way down. Again, do not touch the bottom. Slowly keep swimming around. Whenever you're ready, make
contact with your buddy. Grab your air gauge. Tap on your air gauge to
ask the air of your buddy. Your body will give
the amount of air. Make sure you're OK to it, if
you understand that person. And now the buddy will ask you. Give him your amount
of air and make sure that your buddy gives you
an OK so you understand. Then continue the dive. First thing to do is you
make contact with your buddy and say that you're OK to go up. Then the second thing
is you check the time, making sure you record the
ending time of the dive. The next step is to
go in ascent position, moving your right
hand above your head, and with your left hand,
deflating your BCD. Then check if everything
is clear above you. And then slowly swim up
to the surface, rotating your body, making sure
you keep looking up and nothing is above you. Then once you reach the
surface, fully inflate your BCD all the way to establish
positive buoyancy. Once you reach the surface
in the end of the dive, then make sure you keep your
mask and your snorkel in. Fully inflate your BCD by
pressing the inflator button until the air
releases from the BCD. Take out your second stage. Switch over to your snorkel. Make sure the mouth
piece is down, and then release
the second stage. Start by having your mask on
and your snorkel in your mouth. Make sure that you
fully inflated your BCD. Go flat on your belly,
face in the water, and snorkel forward,
kicking your legs. You can again use the scissor
technique, as shown here, or the frog kick,
until you're done. Start by using the
scissor technique to effectively swim upwards
and keeping your face out of the water. Take out your second
stage, and then inflate your BCD orally by
pressing down the deflator button while you're
breathing in and releasing it in between your breaths. Keep going until your BCD is
fully inflated on the surface. Start by closing off your
scuba tank completely. Turn off the air all the way. Once it's turned off, take
out your alternate air source, hold it with your
right hand, and then your second stage
in your left hand. Purge at exactly the same
time both second stages, so all the air is released from
the hoses in the first stage. Gently put it on the floor. Un-streamline your LPI
hose and disconnect it but pulling back the top of the
LPI and gently disconnect it. Then gently unscrew your first
stage from the tank valve. And then very
important, remember to dry that dust
cap from any water, so no water can enter
your first stage. We recommend using a dry
cloth or towel for this one. Once it's OK, place back the
dust cap on the first stage. Double check everything
from any leaks. And once that's OK, you can use
what we call a spaghetti loop technique to make a
nice little loop out of your regulator
system, and then gently put it on the floor. Release your safety strap. Take it off the tank valve. Then hold onto the
BCD with one hand. Release the tank strap
and remove the BCD from the tank cylinder. Gently put it on the floor again
and make a nice little package out of it. Then grab the tank very gently. Put it on its side on the floor
so it can't fall over anymore. Put your BCD and the
regulator together. Double check if
everything is streamlined. And then you can walk away. Start the skin dive
by having your mask on and you snorkel in your mouth. Take a couple of really
nice deep breaths. And once you're ready,
take a final deep breath and swim slowly down
towards the bottom. Swim under the water
for a few meters, and then when you
reach the surface, clear your snorkel
using the blast method. Keep your mask and
snorkel in your mouth. For the dive
equipment setup, star by inspecting the scuba tank
and check all the numbers on the tank. Especially check the
hydrostatic test date and check your visual
inspection, making sure that all the dates are correct. Check if the the
O-ring is in there and that it is in
great condition. Then check the tank valve,
which way is open and close, and give it a little
burst to clean the valve. Once that's OK, grab your
BCD at the BCD handle. Put your safety
strip away, correctly place the BCD over
your scuba tank. Make sure that's at least
four fingers from the top and then close the buckle. Double check if
everything is attached. Make sure that the tank valve
is parallel with the BCD handle. Place on the safety strap
and tighten the safety strap accordingly. Again, double check
your BCD handle, that it's parallel
to your tank valve. You can also check
if the tank is not too high or too low
by placing your hand and fingers at the top of
your valve and your BCD. To make sure everything
is attached correctly, grab your BCD tank or
the handle of your BCD and then give it
a little wiggle. Just make sure you be
careful of your back. Grab your regulator. Unscrew the dust cap
from the first stage. Make sure that the
two breathing hoses are on the right side of the
right shoulder of your BCD. Place the first
stage over the valve and then gently screw
until it's closed. Now, it's very important. Do not do this too tight,
so only three finger tight. It's all OK if your first
stage moves a little bit before we open up the tank. Then attach the low
pressure inflator hose by pulling back the top off
your low pressure inflator hose and connecting it to your
inflator hose of the BCD. Make sure afterwards,
you streamline it. Once it's all streamlined
and looks in order, grab your alternate air source
and attach your alternate air source at the right
spot of your BCD. Make sure the yellow
is shining outwards. Now if everything looks good
before we open up the tank, turn your SPG away
from you so the glass, in the unlikely
event if it damages, it cannot hurt anybody. Hold down the inflator
button of the BCD, and then slowly
open up the tank, instantly releasing the
inflator button of the BCD. All the way open up
the tank until the end. Now, do a full check
of your dive equipment by fully inflating the BCD first
until air escapes from the BCD and then wait a second. Make sure there's no leaks. Squeeze it a little bit. So now we've checked
that air actually goes in and that there's no leaks. Then deflate the BCD by
releasing all the air. Then check if it also works
orally, by putting a bit of air in there. Couple of breaths is enough. Make sure you press
down the deflator button when you're breathing. Once that's all OK, then
deflate the BCD again. Then grab your second
stage in your right hand and your SPG in your left hand. Clean your second stage
by purging a little bit, then smelling it, making
sure that the air is not contaminated, and then put
your second stage in your mouth and breathe in slowly and
deeply a few times while looking at your air gauge. Your air gauge needle
should stay still. If it moves, then
there is a problem. If it is all OK, then put
your second stage down again, take out your alternate air
source, and repeat the process. Gently breathe in
and out, making sure that everything is OK. Replace the alternate
air source and make sure that everything is
streamlined again. Then after it's all
good and streamlined, gently place your
equipment on its side. Make a nice little package out
of it, as compact as possible. Now, when it all looks good
and done, you can walk away. First thing you do is your
body picks up the equipment. Be very careful about your back. Hold it in one hand
at the tank valve and in the other
hand under the tank. Put the tank on your knee. Then the other person, first
put your right arm in it, then your left arm, bend forward
a little bit, close the Velcro, close the buckle on the
belly, and pull down the shoulder straps. Remember to close the
chest strap as well. Once you're OK, tell
your buddy that you're OK and he can gently let go. Be even more careful
with your back right now, because you have
a tank on your back. Pull up your buddy's tank. And then the same way that
you got into the tank, your buddy can now go
into the tank as well. Again, make sure that
everything looks good and it's streamlined. And now we're ready to
start the buddy check. So remember the
buddy check, BW/RAF. The first thing, you
do the B is from BCD, so inflate each other's BCDs. And check that
nothing is leaking. Then deflate each other's BCDs. Once both BCDs
are deflated, then orally inflate
each other's BCDs, making sure that it all works. Three breaths should be enough. Then deflate each other's BCDs. And then we have the
W from weight belt. Check your buddy's weight belt.
Make sure it's a right hand release, that all the weights
are evenly distributed, and nothing is
twisted or entangled. And vice-versa, your buddy will
after that do that with you. If you have integrated
weights, then check if the integrated
weights are there. Then the R from releases. So check if all the
releases are connected and everything is snug. Make sure it's comfortable,
not too tight, but of course, definitely not too loose. Especially your tank strap,
it's really important that that is connected
the right way. Then your buddy does
it on your equipment. Then we go to the A from air. Now before you take
your second stage, first, check on your buddy. If the tank is completely open,
make sure you look on the valve and check the arrows. And you open it the right way. Once you check on each other
that the tank is properly opened, then grab
your air gauge. Hold it in your right hand
and then with your left hand, take the second
stage of your buddy. First, we want to
clean it by purging it. Then gently purge
it to smell the air. And then breathe from it. Take three slow, deep
breaths in and out. And check each other's
air gauge, making sure that the needle doesn't move. If that is all
OK, then you check your buddy's
alternate air source using the same procedure. Make sure that when
you put it back, that you streamline
everything correctly. And make sure the yellow
is really facing out. Then your buddy does it on you. And again, always double
check if your buddy does the buddy check correctly. Once it's all
streamlined, you want to do the F for the final OK. Now the F means that we want
to double check everything. So make sure that all the
hoses are connected correctly, nothing is entangled, alternate
air source is under the arm, everything is streamlined. And correct any
problems that occur. Make sure that we
have a mask, snorkel. Streamline the SPG. Make sure we have our fins. Now, then a final OK, and
we're ready to go scuba diving. For the Giant Stride,
stand with your toes on the side of the pool
with you fins sticking over. Make sure that everything
is clear below you. Put a little bit of
air into your BCD, 50%. Once that's OK, left hand on
the buckle of your weight belt, right hand, palm of
the hand second stage, two fingers on your mask. When you're ready, look forward
and then big step forward until you go into the water. Once you reach the
surface, keep your mask on and your second
stage in your mouth. First, fully inflate your BCD
by pressing the inflator button until you hear the sound. And then whenever you're
ready, switch to your snorkel and give a big OK to the people
still standing on the side. For the buoyancy
check on the surface, communicate to your
buddy that you're about to perform
the buoyancy check. Put your second stage
into your mouth. Then deflate your BCD while
holding a normal breath. You should sink down
but be neutrally buoyant at about eye level. If that's the case, then you're
properly weighted for the dive. That after you've
performed the skill, fully inflate your BCD again. Make sure there's some
water in your snorkel. Then put it in your mouth
and forcefully exhale to clear your snorkel. Start with your mask
on and your snorkel in. Put your face in the water. Take a nice couple of breaths. Once you're ready,
take a deep breath and switch from your snorkel
to your second stage. Make sure you blow bubbles
in between switching. Clear your second
stage regulator either way you like it,
by using the blast method or purging it gently. Take a couple of
nice, deep breaths. Once you're ready,
take a big breath and switch back to your snorkel. Blow bubbles in between. And clear your snorkel by
using the blast method. Make sure you're next to your
buddy, mask on, snorkel in. And go face down into the water. Slowly start swimming forward. You can use any fin kick by
using the scissor kick or maybe even the frog kick. The distance between
you and your buddy should be around one
arm's length away. Keep snorkeling together. And once in a while,
look at each other to check each other out. And communicate by giving
the OK signal once in a while until you're done. First thing that we do is
we signal OK to go down. Then the second step is we're
going to orientate ourselves by looking around us. And don't forget to
look down to make sure that the area below you
is completely clear. On step three, we're going
to change from our snorkel to our regulator. Make sure you clear the
regulator or the second stage from any water that's inside. Once it's OK, and step four,
we're going to check the time. And then step five, we
equalize, we elevate, and then we press the deflator
button to deflate our BCD. And slowly exhale to descend. Make sure on your descent,
you equalize your ears. Make sure you look
around you and below you. Make sure you communicate with
your buddy on the way down and you stay close
to your buddy. Make sure that we do
not touch the bottom. So go into the
right trim position. Maybe add a little bit of
air in your BCD in the end to stay off that bottom. Once you're perfectly neutrally
buoyant at the bottom, communicate to your buddy again. So the first thing that you do
is to deflate your BCD fully. Then gently go down and try
to lay flat on your belly. Equalize on the way
down if you need to. Then stretch your legs
and try to spread them as far as you can. Take a couple of
nice, relaxed breaths. See if you start to rise
when you breathe in. And if not, then just
put a little bit of air by using your LIP of the BCD. If it doesn't work, just
put a little bit more. Don't worry. You got all the
time in the world. Just breathe in slowly
and you start to rise. While you're going up,
start to breathe out. And then you go back down again. The trick is, when you
go down to start briefing in because there's a
little delay for your lungs to get to the right size
for you to go up or down. Breathe out, we come down. You start to breathe in. And we're going up. Now breathe out. Now go down and breathe in. And you're going up again
and you start breathing out. This way you're not
touching the surface and you're also not
touching the bottom. OK, once you're done, just
deflate your BCD and well done. Start by flooding your mask. The easiest way to do it is
just to pull down your mask from the top until
it's fully flooded. Then with two fingers,
put some pressure at the top frame of your mask. Take a deep breath
into your mouth, in and out through
your nose while you're looking up until all the
water is out of the mask. For the mask remove
and replacement, with your left hand, grab the
mask and with your right hand, take off the strap
and then take off your mask and your
snorkel from your face. Make sure that you hold onto
it and that you don't drop it. Then, make sure the
snorkel's on the side, feel the nose pocket so the
mask is not upside down. Move the strap away and then,
take your hairs out of the way. First your mask on
your face and then you put the strap all around. Make sure it's not
twisted and that the strap is high above your ears. Double check if
everything is OK. With two fingers, touch
the top frame of your mask. Breathe into your mouth
and out through your nose while you're looking up
to clear your mask fully. First of all, with your
left hand grab the mask and with your right
hand the strap. Remove the strap and
then remove your mask and your snorkel
fully off your face. Make sure that you keep your
second safe in your mouth. And you make sure that you
keep holding onto the mask and do not drop it. Stay like this for
at least one minute, slowly breathing in and
out through your regulator second stage. Slowly breathe in and out. Just remember to only
breathe into your mouth and only breathe out
through your mouth. Keep holding that
mask in front of you. To be honest, if you breathe
and slowly and deeply and you breathe out
slowly and deeply, it's actually a
really relaxing skill. You can keep your eyes
open if you want to, but you can also close
them if you'd prefer that. Keep holding onto the mask. Breathe in. And breathe out. Once the minute is finished,
then put the mask back on, first making sure that the
nose bucket is down again, snorkel on the side,
hair out of the way. Put the mask on first
and then the strap. Make sure the strap
is not twisted again and that it's high
above your ears. When everything is in
order, with two fingers, touch the top
frame of your mask. And then breathe into your
mouth and out through your nose while looking up
until all the water is cleared from your mask. Start by grabbing
your air gauge. Have it in front of you
so it's easy to look at. Communicate to your dive
instructor you're ready. And then your dive
instructor will start turning off your air. This will take a
little bit of time. Don't worry. Once the air is
completely turned off, then slowly breathe
in and you will see that the needle will
go down off your air gauge. Very slowly, keep breathing
in until the needle hits zero, which means that
you're completely out of air. Once that happens, give
the clear out a air signal to your instructor. And the instructor will
now open up your tank again and you can comfortably
breathe again. Whenever you're ready, make
contact with your buddy. Grab your air gauge. Tap on your air gauge to
ask the air of your buddy. Your buddy will give
the amount of air. Make sure you OK to it if
you understand that person. And now the buddy will ask you. Give him your amount of air. And make sure that
your buddy gives you an OK so you understand. Then continue to dive. For the first thing for
the five-point ascent is to signal to your buddy
that you're OK to go up. Then the next step is to
check the ending dive time. Then for step three,
going to the right ascend position by moving your
right hand above your head to protect your head and your
left hand on a deflator button. Step four, check if
everything is clear above you. And step five,
we're slowly going to swim up to the surface,
rotating your body, making sure that everything's
clear above you, and keep an eye on your
buddy so you stay close. Do not swim faster than
18 meters per minute. Once you reach the surface, then
keep your mask on your face. Keep your regulator second
stage in fully inflate until air escapes from your BCD. And then switch from your
regulator second stage to your snorkel. And now you completed the skill. First of all, grab the
ladder with two hands. Then put your feet
on the ladder. Make sure that everything
is clear around you and especially
nobody's behind you. Then, slowly pull yourself
up, step for step. With all your equipment
on, climb out of the pool. Grab your fins. By closing off your
scuba tank completely. Turn off the air all the way. Once it's turned off, take
out your alternate air source. Hold it, with your
right hand, and then your second stage
in your left hand. Purge at exactly the same
time, both second stages till all the air is
released from the hoses in the first stage. Gently put it on the floor. Un-streamline your LPI
hose and disconnect it by pulling back the top of the
LPI and gently disconnect it. Then, gently unscrew your first
stage from the tank valve. And then, very
important, remember to dry that dust
cap from any water so no water can enter
your first stage. We recommend using a dry
cloth or towel for this one. Once it's OK, place back the
dust cap on the first stage. Double check everything
from any leaks. And once that's OK, you can use
what we call a spaghetti loop technique to make a
nice little loop out of your regulator
system and then gently put it on the floor. Then, release your safety strap. Take it off the tank valve. Then hold onto the
BCD with one hand. Release the tank strap. And remove the BCD
from the tank cylinder. Gently put it on
the floor again. And make a nice little
package out of it. Then grab the tank very gently. Put it on its side on the floor
so it can't fall over anymore. Put your BCD and the
regulator together. Double check if
everything is streamlined. And then you can walk away. For the dive
equipment setup, start by inspecting the scuba tank
and check all the numbers on the tank. Especially check the
hydrostatic test date. And check your
visual inspection, making sure that all
the dates are correct. Check if the O ring is
in there and that it is in great condition. Then check the tank valve,
which way is open and close. And give it a little
burst to clean the valve. Once that's OK, grab your
BCD at the BCD handle. Put your safety strap away. And correctly place the
BCD over your scuba tank. Make sure that it is at least
four fingers from the top. And then close to
buckle, double check if everything is attached. Make sure that the tank valve
is parallel with the BCD handle. Place on the safety strap,
and tighten the safety strap accordingly. Again, double check
your BCD handle, that it's parallel
to your tank valve. You can also check
if the tank is not too high or too low
by placing your hand and fingers at the top of
your valve and your BCD. Now, to make sure
that everything is attached correctly,
grab your BCD's tank or the handle of your BCD and
then give it a little wiggle. Just make sure you be
careful of your back. Grab your regulator, unscrew the
dust cap from the first stage, make sure that the two breathing
hoses are on the right side, the right shoulder of your BCD. Place the first
stage over the valve. And then gently screw
until it's closed. Now, it's very important. Do not do this too tight. So only three finger tight. It's all OK if your first
stage moves a little bit before we open up the tank. Then attach the low
pressure inflator hose by pulling back the top of
your low pressure inflator hose and connecting it to your
inflator hose of the BCD. Makes afterwards
you streamline it. Once it's all streamlined
and looks in order, grab your alternate air source
and attach your alternate air source at the right
spot of your BCD. Make sure the yellow
is shining outwards. Now, everything looks good. Before we open up the tank,
turn your SPG away from you. So the glass, in the
unlikely event if it damages, it cannot hurt anybody. Hold down to inflator
button of the BCD. And then slowly
open up the tank, instantly releasing the
inflator button of the BCD. All the way open up
the tank until the end. Now, do a full check
of your dive equipment by fully inflating the BCD first
until air escapes from the BCD. And then wait a second. Make sure there's no leaks. Squeeze it a little bit. So now we check that
air actually goes in and that there's no leaks. Then deflate the BCD by
releasing all the air. Then check if it
also works orally. Putting a bit of air in there,
couple of breaths is enough. Make sure you press
down the deflator button when you're breathing. Once that's all OK, then
deflate the BCD again. Then grab your second
stage in your right hand your SPG in your left hand. Clean your second stage
by purging a little bit, then smelling it, making
sure that the air is not contaminated. And then put your second
stage in your mouth and breathe in slowly and
deeply a few times while looking at your air gauge. Your air gauge needle
should stay still. If it moves, then
there is a problem. If it is all OK, then put
your second stage down again, take out your alternate air
source, and repeat the process. Gently breathe in
and out, making sure that everything is OK. Replace the alternate
air source and make sure that everything is
streamlined again. Then after it's all
good and streamlined, gently place your
equipment on its side. Make a nice little
package out of it. As compact as possible. Now, when it all looks good
and done, you can walk away. For the Giant Stride,
stand with your toes on the side of the pool with
your fins sticking over. Make sure that everything
is clear below you. Put a little bit of
air into your BCD, 50%. Once that's OK, left
hand on the buckle of your weight belt, right
hand palm of the hand second stage, two
fingers on your mask. When you're ready, look forward
and then big step forward until you go into the water. Once you reach the
surface, keep your mask on and your second
stage in your mouth. First, fully inflate your BCD
by pressing the inflator button until you hear the sound. And then whenever you're ready,
switch it to your snorkel and give a big OK to the people
still standing on the side. For the buoyancy
check on the surface, communicate to your
buddy that you're about to perform
the buoyancy check. Put your second stage
into your mouth. Then, deflate your BCD while
holding a normal breath. You should sink down
but be neutrally buoyant at about eye level. If that's the case, then you're
properly weighted for the dive. Then after you
performed the skill, fully inflate your BCD again. If you experience a cramp maybe
in your leg or in your foot, on the surface, then
make sure you have your mask and your snorkel in. Grab the top of your
fin, stretch your leg, and pull it backwards
as much as you can. In many cases, it really
works if you do it yourself. But if it doesn't work
out, use your buddy. Now your buddy can do it for you
and can also massage your calf at the same time. Start by signaling to your
buddy that you're OK to go down. Then look around you
and orientate yourself. Make sure that you
also look down, that there's nothing below you. Everything's clear. Then at step three, switch from
your snorkel to your regulator. Clear your regulator
second stage. Then on the next step, check
your dive computer or your dive watch. And on step number
five, equalize, elevate, deflate your BCD to descent. On this descent, we're
doing a visual reference. In this case, we're using
the side of the pool as a visual reference
to slowly go down. Make sure that once in
awhile you look below you, equalize your ears, stay
close to your buddy, and keep looking at
the side of the pool to keep an eye on a visual
reference and stay close. Make sure you don't
touch anything. Once you get close
to the bottom, make sure you don't
touch the bottom and go in perfect
horizontal trim position. Once you're there, communicate
to your buddy to buddy up and to start to dive. During the dive, you might
experience a cramp in your leg. If that happens, make
contact to your buddy and communicate clearly that
you have a problem in your leg. Try to remove the cramp
yourself by pulling the top of your fin backwards
and stretching your leg. But it's much more easier
if your buddy helps you. Massage your calf until
you release the cramp. And then continue your dive. Make sure that you put a little
bit of air into your BCD. Slowly breathe in
and see if you rise. If not, just put a little
bit more air into your BCD by pressing the LPI
inflator button. Slowly breathe in
until you rise. When you start
rising, slowly start to exhale until you go down. And when you slowly inhale,
you will go up again. By breathing normally, you
will stay in one place. Make sure you do
not kick and skull your arms to streamline
it either way you like it by
crossing your legs and putting your hands together. Remember, just breathe in and
out gently on a normal pace. And you should stay in one area. Remember again, do
not touch the bottom. Do not touch the surface. After 30 seconds,
deflate your BCD. And then you end the skill. Make sure that you are
neutrally buoyant by having enough air into your BCD,
gently breathing in and out. Do not touch the bottom. Do not touch the surface. Make sure you're streamlined. Have really, really
good trim by being as horizontal as possible. Scissor kicks are
effective fin kicks, but we do recommend
to use the frog kick. Again, don't use
your hands to swim. Streamline yourself
as much as you can by holding your
hands in front of you or maybe have them on
the side of your body. Keep double-checking that
you're still streamlined, that you don't touch the
bottom or the surface, and that you are horizontal. There you go. Now you're swimming
with a perfect trim. Keep swimming around the pool. And remember, if you go
from shallow to deep, exhale slowly, make sure
you equalize your ears once in a while. And adjust any area
in your BCD if needed. When you realize that
you're out of air, make contact to your
buddy and signal clearly that you're out of air. Your buddy will now supply
the alternate air source. Make sure the hose
is above the arm. Switch over from your second
stage to the alternate air source, blowing
bubbles in between and clear the alternate air
source either way you like. Make sure you stay
close to each other by having a Roman arm shake. Communicate to each other
that you're OK to swim around. You'll be swimming
around for one minute. So make sure you don't
touch the sides, the bottom, or the surface, and have
really good trim together. Make sure that you look at
each other once in a while. But also, briefly interrupted
by looking forward so you don't swim into anything else. Keep staying close together. Keep a watchful
eye to each other. Also once in a while,
communicate to each other if you're still OK. Slowly keep swimming around. Keep communicating. After one minute, signal to each
other that you're OK to go up. Stay close to each other
with a Roman arm shake. Elevate your LPI,
deflate your BCD, and slowly swim
up to the surface. Stay close to each
other and make sure that you keep looking up,
that everything is clear. Once you reach the surface, keep
kicking your legs effectively so you stay up on the surface. Then make sure you
keep having contact. The person that
is not out of air, fully inflate your BCD normally
and help your buddy stay up. And the one that's out of air,
take out your alternate air source and already
inflate your BCD until you're fully inflated
and positively buoyant. Start the CESA by
being neutrally buoyant and in a good ascent position. Right hand above your head. Left hand on the
deflator button. Then take a couple
of deep breaths in. Whenever you're ready,
take a final breath and start swimming slowly
while exhaling continuously, making a sound. [? Aah ?] is the best
sound that you can use. Keep swimming slowly
without touching the bottom or the surface. And keep exhaling, making
that continuous sound. Swim for at least nine meters
until the CESA is finished. Whenever you're ready, make
contact with your buddy. Grab your air gauge,
tap on your air gauge to ask the air of your buddy. Your buddy will give
the amount of air. Make sure you OK to it if
you understand that person. And now, the buddy will ask you. Give him your amount
of air and make sure that your buddy gives you
an OK so you're understood. Then continue the dive. The first thing that you do
is to fully inflate your BCD. Then lay on your back and
open up your weight belt. Then, under water behind
your back, take it off. Remember not to drop it. Keep it close to your body
so you keep your balance. Then make sure that
the weight belt is not twisted or anything. And then put it back. Make sure that you
give the buckle to your left hand and the open
end is in your right hand. Keep laying on your back and
reconnect the weight belt. Make sure that the SPG is not
in between the weight belt. Double check if all the weights
are OK, evenly displaced, and nothing is entangled. --by closing off your
scuba tank completely. Turn off the air all the way. Once it's turned off, take
out your alternate air source. Hold it. Reach your right hand and
then your second stage in your left hand. Purge at exactly the same
time both second stages till all the air is
released from the hoses and the first stage. Gently put it on the floor. Un-streamline your LPI hose. And disconnect it by pulling
back to top of the LPI and gently disconnect it. Then gently unscrew your first
stage from the tank valve. And then, very
important, remember to dry that dust
cap from any water so no water can enter
your first stage. We recommend using a dry
cloth or towel for this one. Once it's OK, place back the
dust cap on the first stage. Double check everything
from any leaks. And once that's OK, you can use
what we call a spaghetti loop technique to make a
nice little loop out of your regulator system. And then gently put
it on the floor. Then release your safety strap. Take it off the tank valve. Then hold onto the
BCD with one hand. Release the tank strap
and remove the BCD from the tank cylinder. Gently put it on the floor again
and make a nice little package out of it. Then grab the tank very gently. Put it on its side on the floor
so it can't fall over anymore. Put your BCD and the
regulator together. Double check if
everything is streamlined and then you can walk away. For the dive
equipment setup, start by inspecting the scuba tank
and check all the numbers on the tank. Especially check the
hydrostatic test date. And check your
visual inspection, making sure that all
the dates are correct. Check if the O ring is
in there and that it is in great condition. Then check the tank valve,
which way is open and close and give it a little
burst to clean the valve. Once that's OK, grab your
BCD at the BCD handle. Put your safety strap away. and then correctly place the
BCD over your scuba tank. Make sure that it's at least
four fingers from the top. And then close the buckle. Double check if
everything is attached. Make sure that the tank valve
is parallel with the BCD handle. Place on the safety strap
and tighten the safety strap accordingly. Again, double check
your BCD handle, that it is parallel
to your tank valve. You can also check
if the tank is not too high or too low
by placing your hand and fingers at the top of
your valve and your BCD. Now, to make sure
that everything is attached correctly,
grab your BCD's tank or the handle of your BCD and
then give it a little wiggle. Just make sure you be
careful of your back. Grab your regulator, unscrew the
dust cap from the first stage, make sure that the two briefing
hoses are on the right side, the right shoulder of your BCD. Place the first
stage over the valve and then gently screw
until it's closed. Now, it's very important,
do not do this too tight. So only three fingers tied. It's all OK if your first
stage moves a little bit before we open up the tank. Then attach the low
pressure inflator hose by pulling back the top of
your low pressure inflator hose and connecting it to your
inflator hose of the BCD. Make sure afterwards
you streamline it. Once it's all streamlined
and looks in order, grab your alternate air source. And attach your
alternate air source at the right spot of your BCD. Make sure the yellow
is shining outwards. Now, that thing looks good. Before we open up the tank,
turn your SPG away from you, so the glass in the unlikely
event if it damages, cannot hurt anybody. Hold on to the inflator
button of the BCD. And then slowly
open up the tank, instantly releasing the
inflator button of the BCD. All the way open up
the tank until the end. Now, do a full check
of your dive equipment by fully inflating the BCD first
until air escapes from the BCD. And then wait a second. Make sure there's no leaks. Squeeze it a little bit. So now we check that
air actually goes in and that there's no leaks. Then, deflate the BCD by
releasing all the air. Then check if it also works
orally, by putting a bit of air in there, couple of
breaths is enough. Make sure you press
down the deflator button when you're breathing. Once that's all OK, then
deflate the BCD again. Then grab your second
stage in your right hand and your SPG in your left hand. Clean your second stage
by purging a little bit, then smelling it, making
sure that the air is not contaminated. And then put your second
stage in your mouth and breathe in slowly and
deeply a few times while looking at your air gauge. Your air gauge needle
should stay still. If it moves, then
there is a problem. If it is all OK, then put
your second stage down again, take out your alternate air
source, and repeat the process. Gently breathe in
and out, making sure that everything is OK. Replace the alternate
air source and make sure that everything is
streamlined again. Then after it's all
good and streamlined, gently place your
equipment on its side. Make a nice little package out
of it, as compact as possible. Now, when it all looks good
and done, you can walk away. For the buoyancy
check on the surface, communicate to your
buddy that you're about to perform
the buoyancy check. Put your second stage
into your mouth. Then deflate your BCD while
holding a normal breath. You should sink down, but the
neutrally buoyant at around eye level. If that's the case, then you're
properly weighted for the dive. Then after you
perform the skill, fully inflate your BCD again. To perform the tired
diver tow, first communicate with your buddy. Ask him if he's OK and
ask him to fully inflate the BCD to make sure
it's positively buoyant. Make sure that everybody has
their mask on and regulator in. Grab your buddy's tank valve
and then slowly start to swim. Make sure you communicate once
in a while throughout the swim and ask if your
buddy is still OK. Keep looking behind
you once in a while so you don't accidentally
swim into anything and keep pulling your buddy. Keep looking, keep
swimming, and keep communicating once in awhile. The swim is for 25 meters. So slowly turn
your buddy around. Again, keep communicating, keep
swimming to the confined water until you finish the 25 meters. First, start by having your
mask on and your snorkel in. Make sure your BCD
is fully inflated. Then, un-do your
chest strap, unclip your belly buckle of your BCD,
and remove the Velcro strap. Stay on your back. Release your shoulder straps and
then gently take off your BCD. Make sure you keep
holding onto your BCD, especially if you
have a weight belt on. To go back in, open up your BCD. Make sure that everything is
clear, nothing is entangled, and once you're ready,
go back into your BCD. The easiest way of doing
it is to lay or sit on top of your BCD. Make sure you don't turn your
body so it doesn't fall off. Put your arms through your BCD. Then close your BCD by
using the Velcro strap. Reconnect the belly
buckle of your BCD. Stay on your back. Pull down your shoulder straps
until it's nice and snug. And do not forget to
reconnect your chest strap. Remember, take your time. Do it nice and slow. If you can't find
it, no problem. Make sure that everything
is streamlined. Double check that
nothing is entangled. Make sure you replace your SPG. Make sure that the
alternate air source is under the arm,
yellow shining outwards. Again, everything looks
good and in order. And then you're done. First, start by signaling
you're ready to go down. Look around you to
orientate yourself. Look down below you to make sure
everything is clear under you. Then, on step number
three, switch over from your snorkel
to your regulator and clear your regulator
from any water. Step four, check your dive
computer or dive watch. Then on five, equalize,
elevate, and deflate your BCD while exhaling slowly. Keep contact with your
buddy at all times. When you slowly
descend, make sure you keep equalizing your ears. Make sure you look down,
that you don't touch anything below you. Stay close to your buddy
and equalize accordingly. Keep communicating to your
buddy and equalize your ears, slowly descending. Once you reach the
bottom, make sure you add a little bit
of air on the BCD to become neutrally buoyant. Get in the right trim position. Most importantly, do
not touch that bottom. Once you are OK,
communicate to your buddy that you are OK to
continue your dive. First you recognize that there
is a problem with your buddy's cylinder tank strap. Clearly communicate
to your buddy that something is wrong
with the connection of your scuba
cylinder tank strap and that you will reconnect it. Ask your buddy to
wait patiently. Then swim behind your buddy. Turn the tank,
readjust, make sure that the tank valve
is parallel to the BCD and that there is at least
four fingers from the top. You can use your knee
to easily readjust your tank whenever it's needed. When it's OK, reconnect
the cylinder strap, double check if
everything is straight, everything is streamlined, and
that the connection is steady. Once everything is
perfectly back into place, communicate with your buddy
again that everything is OK, buddy up, and
continue your dive. For the next skill, swimming
over a sensitive bottom, it is important that you are
in perfect trim and making sure you're
completely streamlined with your equipment. You can put your
arms in front of you and have them close together. To swim around, you can use the
scissor kick or the frog kick. We will recommend the
frog kick if you can. Throughout the swim,
make sure that you check that you don't
touch the bottom accidentally, don't touch the
surface, and keep checking if your equipment is
still streamlined. Keep swimming nicely and slowly. Keep swimming around the pool. At any time, if you're
moving from the shallow end to the deep end, just make
sure you deflate your BCD a little bit, exhale slowly,
and equalize your ears as often as possible. Again, once you reach the
bottom of the deep end, make sure you don't touch the
bottom and stay streamlined. First, take a deep breath in. Take out your second
stage mouth piece down. Blow bubbles and gently
put some air into your BCD by pressing the deflator
button while you're blowing. Then go back to
your second stage. Clear it either way you like it. Take a nice, gentle breath in,
and see if you start to rise. Once you start rising, make sure
that you streamline yourself. Do not kick and skull. So keeping your legs together. Also, keep your arms together. Then, by breathing
in and out normally, you should stay in one place. Keep breathing. Don't hold your breath. Keep checking once in a while
that you stay in one place and that you're not
accidentally touching the bottom or the surface. Keep doing this for
at least one minute. If you want to do it
in a different position like I'm showing right
now in the video, that is absolutely no problem. You can do this in any
position you prefer. You could always adjust the
BCD by letting some air out or putting some more in. But if you do that, you
have to do it orally again. After a minute, completely
deflate your BCD. And then the skill, orally
inflate your BCD and hover for at least one minute. First of all, move
your head to the right. Then remove the mouthpiece
from your second stage out of your mouth. But only do this halfway. Have you mouthpiece on the
outside of your left cheek. Then gently start purging
the second stage to simulate a free flow. While the free
flow is happening, breathe in and out slowly. It's actually very
easy to breathe through a free
flowing regulator. So don't panic at all. Breathe in, breathe out,
breathe in, breathe out. Keep breathing for
at least 30 seconds. In and out and in and out. After 30 seconds, replace the
second stage into your mouth, clear it by exhaling
or any way you like it. If you have some
water in your mask, just clear your mask like
your practice before. Begin by taking off your
mask in neutral buoyancy. Remember to hold onto the mask. And then gently start
swimming forward. You can use your hand to guide
yourself along the bottom, making sure you go
the right direction. Make sure you're
neutrally buoyant, though, and you just swim. And only use your
hand to guide you. Remember, don't drop your mask. If you feel comfortable without
using your hand to guide you, you can just do it fully
in neutral buoyancy. Remember to keep
holding onto the mask and swim for at least 15 meters. Put the mask back
on, first making sure that the nose bucket
is down again, snorkel on the side,
hair out of the way, put the mask on first
and then the strap. Make sure the strap
is not twisted again and that it is high
above your ears. When everything is in
order, with two fingers, touch the top frame of
your mask and then breathe into your mouth and
out through your nose while looking up
until all the water is cleared from your mask. Whenever you're ready, make
contact with your buddy. Grab your air gauge,
tap on your air gauge to ask the air of your buddy. Your buddy will give
the amount of air. Make sure you OK to it that
you understand that person. And now, the buddy will ask you. Give him your amount
of air and make sure that your buddy gives you
an OK so you understand. Then continue the dive. So the first thing for
a five-point ascent is to signal to your buddy
that you're OK to go up. Then the next step is to
check the ending dive time. Then for step three, go into
the right ascend position by moving your right
hand above your head to protect your head and your
left hand on the deflator button. Step four, check if
everything is clear above you. And on step five,
we're slowly going to swim up to the surface,
rotating your body, making sure that
everything's clear above you. And keep an eye on your
buddy so you stay close. Do not swim faster than
18 meters per minute. Once we reach the surface, then
keep your mask on your face. Keep your regulator
second stage in, fully inflate until air
escapes from your BCD, and then switch
from your regulator second stage to your snorkel. And now you have
completed the skill. Start by deflating your BCD. And while you're
deflating your BCD, effectively kick so your
face stays above the water. Then with your right hand,
take off your weight belt and drop it right next to you. Then, while you're now
positively buoyant, lean backwards to end the skill. --by closing off your
scuba tank completely. Turn off the air all the way. Once it's turned off, take
out your alternate air source. Hold it with your right hand
and then your second stage in your left hand. Purge at exactly the same
time, both second stages until all the air is
released from the hoses and the first stage. Gently put it on the floor. Un-streamline your LPI
hose and disconnect it by pulling back to top of the
LPI and gently disconnect it. Then, gently unscrew your first
stage from the tank valve. And then very
important, remember to dry that dust
cap from any water so no water can enter
your first stage. We recommend using a dry
cloth or towel for this one. Once it's OK, place back to
dusk cap on the first stage. Double check everything
from any leaks. And once that's OK, you can use
what we call a spaghetti loop technique to make a
nice little loop out of your regulator system. And then gently put
it on the floor. Then, release your safety strap. Take it off the tank valve. Then hold onto the
BCD with one hand. Release the tank strap
and remove the BCD from the tank cylinder. Gently put it on the floor again
and make a nice little package out of it. Then grab the tank very gently. Put it on its side on the floor
so it can't fall over anymore. Put your BCD and the
regulator together. Double check if
everything is streamlined. And then you can walk away. For the dive
equipment setup, start by inspecting the
scuba tank to check all the numbers on the tank. Especially check the
hydrostatic test date and check your visual
inspection, making sure that all the dates are correct. Check if the O ring is
in there and that it is in great condition. Then check the tank valve,
which way is open and close. And give it a little
burst to clean the valve. Once that's OK, grab your
BCD at the BCD handle. Put your safety strip away. And then correctly place the
BCD over your scuba tank. Make sure that it's at least
four fingers from the top. And then close the buckle. Double check if
everything is attached. Make sure that the tank valve
is parallel with the BCD handle, place on the safety strap,
and tighten the safety strap accordingly. Again, double check
your BCD handle, that it's parallel
to your tank valve. You can also check
if the tank is not too high or too low
by placing your hand and fingers at the top of
your valve and your BCD. Now, to make sure
that everything is attached correctly,
grab your BCD's tank or the handle of your BCD. And then give it
a little wiggle. Just make sure you be
careful of your back. Grab your regulator, unscrew the
dust cap from the first stage, make sure that the two briefing
hoses are on the right side, the right shoulder of your BCD. Place the first
stage over the valve, and then gently screw
until it's closed. Now, it's very important,
do not do this too tight. So only three finger tight. It's all OK if your first
stage moves a little bit before we open up the tank. Then, attach the low
pressure inflator hose by pulling back the top of your
low pressure inflator house and connecting it to your
inflator hose of the BCD. Make sure afterwards,
you streamline it. Once it's all streamlined
and looks in order, grab your alternate air source
and attach your alternate air source at the right
spot of your BCD. Make sure the yellow
is shining outwards. Now, everything looks good. Before we open up the tank,
turn your SPG away from you so the glass, in the
unlikely event if it damages, it cannot hurt anybody. Hold down to inflator
button of the BCD. And then slowly
open up the tank, instantly releasing the
inflator button of the BCD. All the way open up
the tank until the end. Now do a full check
of your dive equipment by fully inflating the BCD first
until air escapes from the BCD and then wait a second. Make sure there's no leaks,
squeeze it a little bit. So now we check that
air actually goes in and there's no leaks. Then, deflate the BCD by
releasing all the air. Then check if it also works
orally by putting a bit of air in there. Couple of breaths is enough. Make sure you press
down the deflator button when you're breathing. Once that's all OK, then
deflate the BCD again. Then grab your second
stage in your right hand and your SPG in your left hand. Clean your second stage
by purging a little bit, then smelling it, making
sure that the air is not contaminated. And then put your second
stage in your mouth and breathe in slowly and
deeply a few times while looking at your air gauge. Your air gauge needle
should stay still. If it moves, then
there is a problem. If it is all OK, then put
your second stage down again, take out your alternate air
source, and repeat the process. Gently breathe in
and out, making sure that everything is OK. Replace the alternate
air source and make sure that everything is
streamlined again. Then after it's all
good and streamlined, gently place your
equipment on its side. Make a nice little package out
of it, as compact as possible. Now, when it all looks good
and done, you can walk away. First thing you do is
with your right hand, hold down the deflator
button continuously. Then with your left hand,
squeezing the RPI hose to the top and then
with your pointer finger and thumb, pull back
the top of your RPI hose and disconnect it. Then gently put it back on
and make sure everything is streamlined. First thing that
you do is you unclip the chest strap of your BCD. Then with your left
and right hand, release your shoulder straps,
unclip the buckle of your BCD at the belly, remove your SPG,
and then open the Velcro strap. But hold onto the Velcro
straps with your right hand to keep your BCD
close to your body. Then with your left hand,
go to your left shoulder strap of your BCD and
get out of the BCD. With your right hand,
grab the tank or your BCD and move it all the way
around in front of you. Now what's important, do
not let go of that BCD. So keep holding onto it. Keep your regulator
second stage in your mouth and just breathe in and
out nice and gently. When you're ready to put it back
on, put your right hand first, it's very important. Then move the tank
around on your back. And then use your left hand to
go to your left BCD shoulder strap. Once you put it back on,
you grab your Velcro straps. Put it nice and snug, not
too tight, not too loose. Then with your left
hand, recover your SPG. Make sure it's under the arm
and replace it accordingly. Clip your belly buckle
of the BCD together. Make sure the alternate air
source is under the arm. Reconnect your chest strap. And then with both hands,
streamline your BCD again. Make sure that
everything is in place, and then you're finished. Make sure that you're
completely negatively buoyant by deflating
your BCD all the way. Then I recommend to have
one leg in front of you to have a really,
really strong balance. Then, open up your
weight belt. Move it behind your back and
then with your right arm, grab both ends of the weight
belt. Move it in front of you and make sure you
do not drop it. So keep holding onto it. Also make sure that you
keep it close to your body so you keep that balance. Then make sure that the
weight belt is not twisted, move it behind your back. Give the buckle
to your left hand. It's very important. Put it back on. Lean slightly forward, it helps. And make sure that nothing is
entangled within the weight belt. Especially
double check your SPG. Once everything is clear,
reattach your weight belt to the buckle. Make sure you get a
right hand release. Make sure that nothing is
twisted, nothing is entangled, and that all the weights
are evenly divided and your SPG is
streamlined again. Whenever you're ready, make
contact with your buddy. Grab your air gauge,
tap on your air gauge to ask the air of your buddy. Your buddy will give
the amount of air. Make sure you OK to it if
you understand that person. And now, the buddy will ask you. Give him your amount
of air and make sure that your buddy gives
you OK so you understand. Then continue the dive. When you're planning
your dive, make sure you communicate clearly to
each other to explain how you want to conduct the dive,
including your descent, how to stay together, and throughout
the dive, all the things that you will be doing. And make sure that
you're doing it safely. For the Giant Stride,
stand with your toes on the side of the pool
with you fins sticking over. Make sure that everything
is clear below you. Put a little bit of
air into your BCD, 50%. Once that's OK, left
hand on the buckle of you weight belt, right hand, palm
of the hand, second stage. Two fingers on your mask. When you're ready, look
forward and a big step forward until you go into the water. Once you reach the
surface, keep your mask on and your second
stage in your mouth. First, fully inflate your BCD
by pressing the inflator button until you hear the sound. And then whenever you're
ready, switch to your snorkel and give a big OK to the people
still standing on the side. For the buoyancy
check on the surface, communicate to your
buddy that you're about to perform
the buoyancy check. Put your second stage
into your mouth. Then deflate your BCD while
holding a normal breath. You should sink down, but the
neutrally buoyant at around eye level. If that's the case, then you've
properly weighted for the dive. Then after you've
performed the skill, fully inflate your BCD again. First thing that we do is
we signal OK to go down. Then the second step is we're
going to orientate ourselves by looking around us. And don't forget to
look down to make sure that the area below you
is completely clear. On step three, we're going
to change from our snorkel to our regulator. Make sure you clear the
regulator or the second stage from any water that's inside. Once that's OK, then step four,
we're going to check the time. And then step five, we
equalize, we elevate, and then we press the deflator
button to deflate our BCD and slowly exhale to descend. Make sure on your decent
that you equalize your ears. Make sure you look
around you and below you. Make sure you communicate with
your buddy on the way down and you stay close
to your buddy. Make sure that we do not
touch the bottom, so go into the right trim position. Maybe add a little bit of
air in your BCD in the end to stay off that bottom. Once you're perfectly neutrally
buoyant at the bottom, communicate to your buddy again. First of all, communicate
that you stay close together and that you are going to
swim around in a mini dive. Make sure that
you're streamlined and that you have
the right trim. At one point, make
contact with your buddy and ask your buddy for the air
while tapping the air gauge. Your buddy will now
give the air signal. And then you clearly communicate
that you understand it. Now you switch roles, where
your buddy asks for your air and give the
appropriate air signal. Once your buddy agreed on
it, you continue the dive. Keep swimming together. Don't touch the bottom
or touch the surface. Once you're ready,
tell your buddy that there's a
problem with your leg and that you're having a cramp. Be a team and release
it accordingly by scratching the top of
your fin, massaging the calf, and help each other. Keep swimming. Then repeat the same
skill which your buddy. So during this mini dive,
you're repeating the skills that you practiced before
while actually simulating that you're on a dive. Cool. All right. So when both of the
cramps are released, communicate, stay
together again, and continue your mini dive. At one point, make contact
again for another skill. In this case, adjust
for neutral buoyancy. Then once you're
OK, you're going to signal that you have
a problem with your mask and it's foggy. Clear it by putting some water
in the mask and fully flood it. And then gently clear your mask
by breathing into your mouth and out through your
nose while looking up. While you're swimming
around, at one point, make contact to your buddy
again to practice another skill, in this case, out of air. Clearly signal to your buddy
that you're out of air. Your buddy will present
the alternate air source like presented before. Switch over from your second
stage to the alternate. Make sure you blow bubbles. Stay close to each other
by using a Roman handshake. And then signal to
each other that you're going to be swimming around. It's very important that
you stay close to each other so that you don't lose
the alternate air source. Make sure that you're
neutrally buoyant and that you're streamlined. Keep looking at each
other, keep communicating, and keep swimming. Again, breathe in and out nice
and slowly and deeply at all times. Keep swimming,
keep communicating, keep looking around you, making
sure everything is clear. Keep going. All right, once it's time to
go up, signal to your buddy that it's time to go up. Then stay close to each
other, elevate your LPIs, deflate your BCD. Slowly swim up to the surface. Once you reach the surface,
it's very important that the person who's
not out of air fully inflates the BCD
using the LPI button. And keep having contact
with the person out of air and help him out of the water. The person out of air, remove
your alternate air source and then orally inflate
the BCD all the way until you're positively buoyant. And then you completed
the mini dive. Well done. Check your dive computer
and signal that you're doing a safety stop. Check your computer
again and make sure that you stay at
the right depth. Also, the computer will track
the time of three minutes. Keep being neutrally
buoyant and simulate that you are in a safety
stop for three minutes long. So the first thing for
the five point ascent is to signal to your buddy
that you're OK to go up. Then the next step is to
check the ending dive time. Then for step three, going
to the right ascent position by moving your right
hand above your head to protect your head and your
left hand on the deflator button. Step four, check if
everything is clear above you. And on step five,
we're slowly going to swim up to the surface,
rotating your body, making sure that everything's
clear above you, and keep an eye on your
buddy so you stay close. Do not swim faster than
18 meters per minute. Once we reach the surface, then
keep your mask on your face. Keep your regulator
second stage in. Fully inflate until air
escapes from your BCD. And then switch from your
regulator second stage to your snorkel. And now you've
completed the skill. First of all, make sure
that you're positively buoyant by inflating your
BCD all the way until the air escapes from the BCD. Then take off your weight
belt and put your weight belt on the side of the pool. Make sure you do a gently so
you don't damage the pool. Then unclip your chest strap,
release your BCD shoulder straps. Make sure that
you have your mask on and your snorkel
in at all times. Then take off the Velcro
and take off your BCD unit. Keep holding onto your BCD. Put your SPG on the
side of the pool so your BCD doesn't
float away and secure it with your weight belt. Then
swim to the side of the pool. Put two hands on the
side of the pool. And then kick upwards to easily
take you out of the water. Sit on the side,
take off your fins, put your fins on the side, take
off the mask and your snorkel, and gently put it
on the side as well. Then get out of the water. Take the weight
belt off your SPG. Grab the BCD at the
handle with one hand, with your other hand
at the tank valve. Be careful of your back. And then gently take your BCD
and your tank out of the water. Then deflate your
BCD all the way. Streamline your dive
equipment as much as you can. And gently put it on its side so
that the tank cannot fall over and it cannot hurt
anybody or the equipment. Again, streamline everything. Make a nice little
package out of it. Put the weight belt on the side
of the tank so it cannot go anywhere. Once everything looks good,
then you can walk away. --by closing off your
scuba tank completely. Turn off the air all the way. Once it's turned off, take
out your alternate air source. Hold it with your right hand
and then your second stage in your left hand. Purge at exactly the same
time both second stages till all the air is
released from the hoses and the first stage. Gently put it on the floor. Un-streamline your LPI hose. And disconnect it by pulling
back the top of the LPI and gently disconnect it. Then gently unscrew your first
stage from the tank valve. And then, very
important, remember to dry that dust
cap from any water so no water can enter
your first stage. We recommend using a dry
cloth or towel for this one. Once it's OK, place back to
dust cap on the first stage. Double check everything
from any leaks. And once that's OK, you can use
what we call a spaghetti loop technique to make a
nice little loop out of your regulator
system and then gently put it on the floor. Release your safety strap. Take it off the tank valve. Then hold onto the BCD with one
hand, release the tank strap, and remove the BCD
from the tank cylinder. Gently put it on
the floor again, and make a nice little
package out of it. Then grab the tank very gently. Put it on its side on the floor
so it can't fall over anymore. Put your BCD and the
regulator together. Double check if
everything is streamlined and then you can walk away.
