Ahmed what type of gear gets in the way of ratio deco?
Gases I can understand but gear?
Richard
A major factor is that ratio deco on deeper dives really needs a greater variety of gasses. More stages means more technique needed to handle them. Regular gear is really not designed to carry that much kit under water. You actually need less to carry more. That is one reason why DIR is a suitable approach that ratio deco fits in well with.
Now the problem that jumps up here is that you rarely find a person doing a TDI class that thinks along the DIR way. But once they see the reason behind the madness (we don't use lots of d-rings for example), they normally come around
A small example: the divers note book becomes an inseperable peice of kit as well. Much better than the wrist slate when used properly. It really needs to be stowed in your right thigh pocket to have easy access for you and your team mates. In many cases, a TDI diver, will not have really seen need for thigh pockets as it is likely that they are taught to stow gear on the stage tanks.
I have made a decompression workshop for experianced trimix divers that gets all that clear. It dose take 4 to 5 days though. But after which the diver has a real clear understanding and a chance to do some nice deep practice dives

My previous students have been coming for it and they love it! Although they hate me for the computers I had sold them on their previous visits!!!
Sorry for the long post.
