I think I'd be concerned with isolating and solving the problem at the stages, without involving my primary source of bouyancy and thermal control. >The dry suit inflation (if needed you are at 70 feet and rising at this point) >could be solved just by reconnecting the hose once its on the deco tank.

I'd find it easier to maintain a nice steady ascent rate and run time if I had to just unscrew a reg in front of me. I think I'd have to stop and hang on or clip into the up line if i were to try to get a reg off from behind my shoulder. >Instead of pre forming several tasks at once wouldn't it be easier just to stop >and sort out the problem and move on.

But with the stages in front of you, unscrewing a reg is no more difficult than unstowing a john line or reading the tables or any of the other things we regularly do while ascending. >Another point to add here is what if it was a two gas dive? Then the option of >the other deco reg is not there. Then you would have to switch back for stage. Well I was thinking through the dive you described with two or more deco gasses. With a two gas dive, I'd just deco out on the back gas. If I had to go to for the left post reg, seeing as I dive 300 bar DINs which sometimes need two hands to wrok undone, I think I'td be quicker and easier if I just swam over and unscrewed Jim's. rgds billyw >bdi wrote: > >> At 02:24 PM 15/3/99 -0500, Craig Waldman wrote: >> >> >From: Don Mason <deep6@se*.co*>>: >> >> >> Imagine your doing a three gas dive.
