How to become a Technical diver, PART 2:3 The equipment

you hi and welcome to this second episode on how to become a technical diver if you haven't watched the first installment of this three video series just click right here and it'll take you to a link to the first video and the second video is about equipment what kind of equipment do you need to do technical diving so join me and I'll go to it step by step obviously we need some tanks so doable 12 is a preferred tank size in Europe these are readily available if you're over in the States it might be a twin 80 cubic feet or low-pressure 110 s or something like that but roughly the equivalent of twenty four liters of means 4800 liters of compressed gas so double 12 in this case is it's perfect no boots no nets not necessary just a manifold the doubles like this make sure your valves are all nice and lubricated so they do nice and they turn nice and great and for that I have another video I'll link it in the description down below how you service these these valves so but the tank alone doesn't get us there we also need to wing voilá one wing so what we need is a wing between 18 and 25 liters of lift a single bladder wing with a short inflator hose I mean not one of these long ones that extend all the way down here a dump valve no plastic rubber thingy just a piece of string two d-rings on your chest one d-ring on the left hand side I've gone for the small half d-ring on the left-hand side as well that is something we learn from sidemount diving is when you're dqo or staged models become very light after you use them you can move them one level down and they stay better in trim beside you that's a nice little pro tip and obviously is a crotch strap with a d-ring in the front for a scooter and a d-ring in the back for accessories when you think about the harness it should be a single piece harness no buckles no clips no adjustments needed we'll set it up correctly and you'll be good to go again there's another video on how to set up a dir harness I'll put that also in the description down below there are some systems with a it's just like some call it a king system some it's an adjustable harness where it's still one piece those are okay but I only suggest those if you really switch between them almost Arctic diving with a dry suit full with underwear or tropical diving where you're diving in a when you use the backplate and harness on a single tank wing with the thin wetsuit but now the other case one adjustment for the harness is enough for all kinds of diving that's what I use on the side of the backplate you can see there's a little attachment mounting hardware for the argon bottle so obviously we also need an argon bottle and there's the argon bottle we call it an argon bottle but usually in reality it's filled with air you can fill it with argon but it'll give you a marginal gain it takes a lot of you know flushing of the inner suit for the for the maximum gain to be reached when using argon so normal air is just fine it's mounted with the one strap around the little tank here in this case it's an aluminium tank 0.8 meters and a little bungee on the bottom part of the back plate which is just loosed around the valve like this on the dry suit inflation tank that's obviously a little regulator you can use a little tiny compact first-stage with an over pressure release valve the shortest inflator hose almost as you can get I will mount it there normal thin valve as you can see the hose is routed underneath the hip strap if when you put the suit on and the harness on it'll go straight on to the valve so it doesn't go underneath this like it normally would when it comes from the left post so straight doesn't interfere with your d-ring that way it's routed correctly then what about the regulator's let's start with the right side you're right primary regulator holds the inflator hose for your wing and your long hose long hose is rather a streamlined down as possible and the same goes for the inflator hose make sure that the length of the inflator host matches the length of your low-pressure inflator now I would suggest having these like inner tube bungees on your set so that you can keep everything nice and tidy and then the bungee that actually is attached to the left chest d-ring goes over the low-pressure inflows but not also over your inflator hose from your regulator that way it can never get lost behind your shoulder because it's stuck there the reason why we don't put it all the way over here or over both is that it can keep it caught and then dislodge your inflator coupling and you don't want that to happen so we either do it on only over this one or only over the low-pressure inflator just to make sure that you don't dislodge your inflator coupling now for the left post the left post regulator holds our necklace second-stage it holds our SPG doesn't have to be a very long one just as short as you can go about it it keeps nice and tidy to your body and if you are not diving with trimix and inflator hose for your dry suit in this case it's a little bit longer one with an air gun because I use this for training purposes when use the airgun to simulate realistic failures on the twin sets underwater training the necklace bungee is zip tied onto the mouthpiece so in this case I've just replaced the zip tie that holds the mouthpiece on originally with another one and I incorporated this bungee this is a nice what they call surgical tubing bit old-school like that but you can use any type of bungee just don't go too thick it needs to be reasonably flexible make sure it's in there permanently so it's not one of those that just moves over the mouthpiece that you can pull out because this one is not to be shared it is only for you around your rectus so a permanent nice necklace that's not too long and permanently attached you're good to go what about accessories well we need lights for example we need a primary light and at least one backup light in non overhead environment diving a one backup light suffices two backup lights are nice if you do overhead environment - and backup lights are necessary both the primary light and the backup light if you only has one go on the right and the right chest d-ring I've removed the long hose for now so you can see I put my primary light on the inside is that way I can reach it with my left hand and I put my backup light in the middle now my long Eilis can come on the outside this way I know they the order in which they are the backup light is just mounted with one of these bungees on the webbing that way it keeps it nice and tidy the secondary advantage to doing that it is also keeping the d-ring down so it's easier to clip on and clip off the primary light should be a strong light it can either be a canister light like this where you only hold the light source in your hand and the battery is attached to harness nowadays battery capacities are so good that you get really strong long-lasting primary lights that are one unit so those are also a possibility so that's almost done for the almighty twinset if you're diving in a side mount configuration I personally like the utd Zed system because it's the most consistent when it compared to the side mount system or whether with the back mount system so because everything is roughly the same the long hose comes from the right side necklace from the left side the harness is the same all the things they consistent what do we do for weights if the weight of the tanks and the back plates is not enough we can add weights to this we can use a V weight which is like a v-shaped weight that ain't that basically goes in between your tanks or you can use a tail weight which is usually also V weight but it goes lower on your tank and you can add those if necessary you could just use a normal weight belt but usually the weight of the tanks and the back plates offset enough weight for you to use this tank set as it is obviously we need decoy and stage cylinders D Casilla are used for the decompression part of the diving and stage cylinders as part of the bottom gas a stage cylinder is an unmarked cylinder meaning there's no depth based decals on the sides of the tank just an analysing label otherwise the tank is completely cleaned a deacon cylinder has a depth decal in this case oxygen 6 meters this is a bit of a hack with a piece of tape because his rental cylinders here from local dive centre and obviously the analyzation label but this is what you can tell the difference the regulator is just needs to be a good o to service o2 cleaned regulator with a 1 metre hose and a short 15 centimeter hose SPG it can be what then they make you want just make it shoot make sure that it's all too clean and that the hose is 1 meter long the stage kit is a stage kid made of with one piece of string with a tank band here and two rubber bungees to keep everything nice and tidy so you don't need any clips or anything balls or any other stuff in there just two rubber bungees and the kit and I've also made a video on how to make this kit yourself and I'll put that link in the description down below as well the way we've attached this SPG to this first stage is by using a bungee and the bungee is just basically a little loop let's see if I can take it off a little loop like this which is roughly the same size as your hand and that way you can actually easily detach the bungee and the SBG that way you can relieve the pressure of this high pressure hose a little bit because they get you know worn and put on a lot of stress if they're completely tight wound up all the time so this way you can just easily replace or relief attention this bungees dough stays there like so and you can also use that that when you have the tank this mount or the regulator is mounted from your sit you can hang it on the valve like this and it doesn't hang in this and it's very handy little trip then when you need it all you do is you attach first stage move your SPG in place and keep it in place by the little Bungie happy days size-wise I prefer to use 240 cubic feet tanks for either night trucks or nitrix 50 or 100 percent oxygen you can use an 80 cubic feet as well as a nitrous 50 bottle or as a stage bottle this is a seven liter tank personally I prefer to use either 40 or 80 s because of buoyancy characteristics but as long as it's an aluminium tank you're good to go expose your protection what do we need there well 99% of your technical diving is gonna be done in a dry suit and mostly because of balanced rig issues because when you dive deeper down it gets colder your wetsuit gets compressed and you all know the story about the balance rig again comes a theme in this video I put a link in the description explaining why we don't dive deep in thick wetsuits so when I look at that dry suit we want to look at a try lemonade dry suit means it's like a shell dry suit either that or a reasonably thin neoprene it's also doable but primarily try a lemonade dry suit we advise to large cargo pockets on the sides and let's look at what's in those products here we are all the pockets contents displayed out let's start with the right side pocket our primary pocket in the primary pocket we'd usually have the things we expect to use on the dive mmm-hmm but always we have our SMB in there are wet notes I have a leash in the top flap here and then extra double ender never know when that comes in handy but you can put all sorts of stuff in there if you have a small real you know you're gonna use on the dive put it in there a small camera put it in there anything you know you're gonna use on the dive you can put it in there it fits obviously so right side is our primary pocket everything is attached in the pocket on these bungees so there is bungy loops in every compartment of the pocket like a bungee loop here punch it up there and in this nice pocket it has the designated place for the webnode a nice little you know thin low-profile pocket inside on the Left pocket which is considered to be our backup pocket we'd have our backup mask also on a bungee this is a blender I have a pair of scissors or a backup cutting device backup spool or safety spool again an extra double ender and in this case I have a what you call the john line it's basically a piece of flat string here that I can attach to an upline if there's a current and I am free of holding on to the upline and I can use a john line instead of my hands makes gas switching a lot easier now last but not least we need a mask obviously low volume mask that fits you well with a neoprene strap strap preferably I'm not silicone it comes with our fins short stiff rubber fins short and stiff because we like it because it gives us a better feedback with the water stainless steel springs or rubber Springs or whatever anything like springy so we don't have to have these flaps adjusted and the stainless steel springs they never break these are about 16 years old instruments a bottom timer and a compass bottom timer can be also one of these nice ones with a LED display or something like that but anything they can tell you dipped in time and a compass for direction that's all you need now I show these in in one go because what I usually do is I fold up the strap of the mask like this put my bottom timer and my compass in there and the whole package goes in my fin pocket this way it stays nice and compact and nice and protected and then I take my hood and I roll the hood up and it goes in the other fin pocket off we go finally when you want to do technical diving it's a good idea to invest in your own analyzer if you want to go all in and helium analyzer is very nice especially if you travel around and you don't want to rely on the diving stations having a reliable helium analyzer they're not cheap but hey diving isn't cheap so I had a spares box I mean it's Paris box with some piece of string some seals for the dry suit some or ink it's for the regulator but the blue valves you know do whatever you know go all in if you want I mean there's tools inside extra hoses extra SPG's just them you know make it as complete as you can afford the trucks when we're making a video you
