In principal I agree with you. I suspect the deco obligations would be pretty varied depending on what you use to calculate them. I have dived to 60 mrs on a single 12 ltr but only spent a minute or two there. His air consumption can not really be calculated in advance - for example, depending on his planned rate of ascent from the bounce he may well be exhaling all/most of the way. By my own stupid fault I have accidentally dived with a ppO2 of 3.2 for several minutes - I have no idea how much longer I would have lasted before ox toxing BUT I felt no ill effects up to that point.

Yes, he has the right to dive, but surely the industry has a duty of care to make sure they know the risks they are taking.

Yes, I would agree and would have thought, for their own security, the dive centre in question would have at least requested a written disclaimer from the diver in question. Of course, he may not have said anything to anyone and just "gone for it".

In the meantime, sadly, the powers that be don't view the situation as we do, and as AndyP states, it might jeopardise other, eminently more sensible divers, doing the dives properly.

Sad to say, that may be the official response. It should not be the case though. Were I "the authorities" I would make sure that the relevant dive centres warned ALL divers of the dangers and that all divers doing deep (below 50 mtrs) air dives need to leave a "blank cheque or credit card slip" as a recoverable deposit to pay for the recovery of their body in the event of their death.
