When 4 divers sharing air from a tank is not considered as buddy breathing?
EDIT: I really am confused about this.
Buddy breathing has pretty much been eliminated from modern OW instruction because it is considered too likely to result in a double fatality.
Glen Egstrom, Berkeley professor and one time director of NAUI, studied buddy breathing decades ago. He determined that for a buddy team to be able to perform the skill confidently under real OOA circumstances, they would have had to have had about 17 successful practice sessions prior to that. He also determined that the skill was perishable--that buddy team would have to practice it regularly to be confident they could do it in a real situation.
I would not do it with anyone on a safety stop. I would just head for the surface. the odds of a problem occurring because of a missed safety stop on a recreational dive are close to nil.
If for some incredible reason I was somehow involved in a buddy breathing situation at depth on a recreational dive with someone I barely knew (as in this situation), I would let the other diver have the working regulator, and i would do a CESA to the surface. that is a lot safer than having that diver kill me.
I believe the story.Correct--the safety stop was not a good choice, but if a DM and 3 of his clients went OOA on a dive, then that would have to be the most incompetent DM in the entire history of Cozumel diving.
That was the best gut laugh I've had all day. Yes it really was that crazy. I imagine that the rate of consumption off that single first stage reg was about the equivalent of a panicked big guy at 130'. I couldn't last long and I would have skipped the safety stop and cesa'd to the surface where they would have found me waiting for them. This was a normal rec dive in Coz so there was no obligation at the safety stop just a never ending stream of bad judgement that all worked out ok in the end.They were not buddy breathing they were using another divers octopus.
OH WAIT
Never mind I get it now

can you elaborate?
Why not a safety stop? If they've got a few hundred psi in each of the two remaining tanks that's probably going to be enough to sit at 15' for the better part of 3 minutes, and if they had just ascended from a deep dive why not use the gas if they have it to avoid a possible case of DCS?
