Dave,

In the main, I agree with a lot of your thread. However my KISS style DOCCR was designed to do 100MSW, far deeper than I would want to to do 21% diluent O2, even for short periods.

I say this because I almost toxed once (sypmtoms of diaphramatic and facial twitches) with a PO2 of only about 2 for less than 10 mins.

You are also correct in pointing out that when you do have a problem and swith to SCC , you are on the move. A lot of the divers who monitor this forum don't know their individual tolerance levels on a good day let alone a bad one. Some of them would have a problem recognizing a problem early enough to impliment your approach safely.

I see problems with your approach, which in the hands of less experienced divers could quickly make a bad situation worse. You have to remember your experience level versus the main when promoting a different phylosophy.

I don't often disagree with most of what you say, but this this time I have to stradle the fence a little on the other side.

Dale

hey Dale, am interested in your toxing at 2. for less than ten mins, I also like dave hit the bottom semi-hot sometimes 1.6-1.8 shut off the valve at my hydrogom, metabolize it down (few mins) turn back on the constant flow and continue diving, in your situation, were you stuck at 2. for however long, could you give more details, and what you did to fix the problem, very interested, because you dive a kiss style like myself. thanx.
