DrySuits

[PfcAJ]

The thing about argon purging is that ~20% improvement tests were done at 1ata.

On on a deep dive you're decanting the air in the suit with argon as you decend. The amount of argon present on a deep dive is pretty high, even without a 1ata suit flush.

On long dives, I take the argon. And a thick hood. And a fresh(ish) undergarment. And base layer tops and bottoms. And a heated vest. If you're on the hook for some serious deco, all the pieces need to be in play.

Can't rely 100% on that vest. Too many variables.

On a shorter/shallower thing without a ton of deco, sure, rock that vest and maybe omit some of the other stuff. If it breaks no big deal.

Anybody uses Waterproof D6 Lite? I've tried to find any real comments with no luck, just ads.

I signed me up for drysuit course as it was a suggestion of the Instructor that will be teaching me the AN & DP, and because it is very cold in the lake where eventually I will do those courses if everything works out right, as well do to the redundancy of wing and drysuit or something down the line I understood around the subject, and I have some questions for you guys related to this.

When he ask me what kind of gear I had a gear for doubles, I told him that I have a kind of hybrid BC Wing or recreational Wing that can carry 3 bottles, and explain to him that I can make it side mount or single back mount but he was not familiar with that type of gear, in our conversation I ask him if it was a option to carry the two depth mix on the sides and the high O2 on the back he told me NO WAY, I didn't ask why. .. Does't it have to do that it is safer to keep your High % O2 at eye site since this is the gas that will be crucial for the Deco ? I ask because if I have two bottles of Depth mix I can keep breathing from both tanks and keep my trim balance but If I have O2 on one side and Depth mix on the other, will it not be that I will begin to tilt to one side as the mix gas is consumed ?

Other question, since I will do the course in a lake, the buoyancy control in the dry suit will be a little harder to control in order to get the trim right correct ? I did dive Nemo 33 and it was my first time in fresh water so I did not had a perfect trim in control, contrary than in salt water where I don't have a problem with my trim.

It's not harder to control the dry suit due to being in fresh water. But practice enough before starting to do deco dives!

Actually 3 reasons the instructor give me, one the cold when Deep for extended periods of time like doing Technical diving, more because the lake is very cold and we can reach 4*C later during tec courses, second reason was redundancy in case the wing fails if you use a single chamber wing, and the other of course is that he wants to see how I dive since I have only 40 dives.

And how many in a drysuit?

Blowing deco because you were too multi-tasked to control your buoyancy is a very bad thing. You are going to need water time in a drysuit, if you aren't ready once they add failures, guidelines, lost deco gas, no mask.......etc......you won't have time to think about buoyancy.

The Instructor said the same thing, more fly hours, if I will do a deco dive it will be in the caribbean more likely, no need of dry suits in the dives I want to do, it happen that I'm here in Nederland and I will take the advantage to do my Tec courses here, but because it is cold here I can't do these courses without the drysuit course first.

I was planning for redundancy lift with a BA bouy in hot waters, since I don't have a drysuit.

The instructor will put me to the task in recreationak conditions, he want to see how I dive before he grants any Tec training.

Very wise instructor, but I would be thinking that you need more dives under your belt before starting tech.

Why do you say that? Many new divers up here in Canada, learn to dive with drysuits from their first dives during ow classes. Wetsuits are not really adequate protection for the temps in our waters. Many still however do dive wetsuits here though, Brr. Also many of us started down the road to tech from dive one, keyword is started.

Personally, I applaud the op for wanting to learn how to use a drysuit early on. In fact it's people like that I'd gladly take under my wing and mentor as they are keen to dive and sadly this sport is loosing a lot of people to other sports/hobbies.

Getting instruction on the suit is hit or miss, too many shops teach divers how to use drysuits incorrectly (ankle weights, as primary buoyancy devices, etc) and they pass along these bad habits and think that stirring up the visibility/etc as their fins are pointing down is acceptable. There is a shop here in town who does this and I've never seen such poor divers in the water, many times I've want to swim over and unclip the ankle weights as I'm sitting there on deco hovering and they just swim buy churning up the ocean floor and running the visibility for the rest of us.

Instructor approve for me to continue in to Tec, but he was very clear to tell me that doesn't guaranty that he will pass me, I have to get everything right, which is totally understandable and I respect that phylosophy. The bad thing I will need to do the AN & DP in 12 dives double of what is normal, which is actually not bad but it will eat money for traveling and gas.

I guess he will hammer the tec in my soul so I don't Fu#$€*
