in those situations would you not have individual bailout for that situation and then team stages? Never heard of doing team bailout while in restrictions. You would typically plumb a BOV into your dil tank if you have one, then have usually an AL40 as on-board bailout for you. If you are planning team bailout in those situations you're crazy, I have no issues with team bailout, but not when you're in any sort of restriction.
Just playing the Devil's advocate.... Not necessarily a restriction as such, I'm talking low, narrow tunnels, like the catacombs in Ginnie or the water source tunnel in Peacock. in Ginnie. They go quite a ways before opening up. My instructor teaches both team & individual bailout. He prefers individual, but does teach team bailout to comply with standards. I do not have a BOV on my unit. Purely offboard bailout on my part. I am being trained to dive with 2AL 80's. I agree, some dives DO require different gas planning, no doubt.
