I like low PO2s also, but O2-induced convulsion, in my opinion, is a relatively *minor* risk for these 300+ foot air dives (please, before anyone flames, note that I said "relatively"). A whole bunch of people have been asking me my opinion about the big "stunt" exposed in the recent A/C. The critics always point to high PO2 and the lack of redundancy as the big "violations". Folks, get this clear - far and away the MOST dangerous thing about dives to such depths on air is the mental and physical incapacitation from narcosis - NOT O2 toxicity; NOT lack of redundancy. Sure these are risks, but they are DWARFED by the risks from incapacitation. It's like comparing the risks of an accident due to a broken tail-light on a car to the risks of an accident due to a severed hydraulic brake line. This is especially true of the redundancy thing - the probability of the "wah wah" (which, incidently, is the diver's heartbeat) leading to "la la" land is WAY higher than the probability of a regulator failure. Remember - Raimo was the only one with a 2nd bottle, and he was the one who almost bought it.
