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.
