air2, atomic SS1, ect...

99,99% of my dives are cave dive & sump dive, but know my kids want to dive. I do my first dive with one and try an air 2(it's a friend equipement) ,a configuration with one hose for the primary regulator , one for the air2, is a clean configuation. Why dir diver don't use it in rec dive ?
Regards

There are a number of reasons, The main one being it's not part of the standardised equipment setup.

In order to be able to breath from it and move your head they end up being on a longer corrigated hose, which added to the fact the inflator/regulator is bigger and heavier than a standard inflator means that it will dangle down below the line of the diver, and therefore be a bit of a line magnet. It also means that you need to try and control your buoyancy with the thing in your mouth which is not as easy as it might first seem.
Then comes the question of where do you route it from (Left post or right post) If you route it from your right post, then this is the same as your long hose, but if you route it from your left post then you have to route your drysuit from the right post, and suddenly we're changing a whole load of stuff between rec and tech diving. That's not the DIR way.

Yes at first it seems to be a good idea but in reality it is just a convoluted invention. It is trying to go for the 2 in 1 formula, like shampoo and conditioner, but then it is neither shampoo nor conditioner.

First of all welcome, not many French(-speaking) divers are into DIR, or they just do not know much about it.

I am just freshly packed from my fundamentals class. The thing I liked is that you always dive the same (sort) of set up in "DIR-style". I was lucky enough to start diving in a DIR way after only 13 dives. This means that I never really got used to anything else. All the reflexes I learned from the start, will serve me all through my diving career (where ever that may take me).
I had 80 dives on taking fundies, only 3 of which were in doubles (once D7, twice D12). I took a chance using in doubles for the class, and it turned out to present no problems whatsoever. All I needed to do was change my weighting, and the first couple of times the dumpvalve was not quite where I expected it.
Some explanations for the way things are done seem a bit far-fetched for somebody starting of in diving, but it is all done so that later bits can be added without having to change an old habit.

So: why change to a more "recreational" (???) way of diving to go with your child? Just use what you are used to, save perhaps using a pioneer/eclipse and a single tank.

I practice to sort of cave diving. My first sport is caving and i use sump diving like a tool(like climbing, explosive , ect...) i dive solo( 2 bottle in a kit bag, helmet, ect ...) i'am ok it's not dir, but when the dive is after 300 meters on vertical ropes, 12 hours of walk you don't have the same aproach like diving a florida cave when you can put 2 pickup wheels in the water

My problem came when i start to do"classic cave dive" in lot, Ardéche ,Mexique . I dive with my wife , my friends and i realize i dive like a solo diver but i'm not solo in the cave i'am with an other diver . And the worst thing is to mix 2 sort off diving conception: the guy with you think: cool he could help me if i have a problem , but i'am a solo cave diver and i have no experience for that. So i'am looking for DIR diving because i think it's the best system for dive with a group.
Why an AIR2 :Because it's one hose less.
Sorry for my english: i know it's very bad.

Well..you said you want to start with DIR, so read some of the advice on this site, and GUE.

DIR is not only about equipment, it also about team work, so no solo in the DIR system, and about your mentality about diving (mindset) your body (good phisical condition, no smoking)

And when you look at the equipment, Bob Coopers piece is great about it (Are you Doing it Right?) you see that there is no place for an AIR 2 or a variant on it.

So do some reading, ask questions, so you know what DIR is and means ;-)

Bon voyage sur la routier s'apppelle DIR
