My PADI OW text says to use CESA (controlled emergency swimming ascent) at depths down to 30 feet in OOA situations (and no buddy). [You know the technique--swim up saying ahhhhh all the way.]
But a commercial diver I was talking to said he's done a CESA from 100 feet. Is that credible? What's the greatest depth you've done or know someone's done?
The answer is important because below the greatest depth (whatever it is), PADI says to drop weights and make a buoyant emergency ascent, risking DCI as the lesser of two evils. If the greatest depth is actually around 100 feet, then I don't need to take a pony along for resort diving.
OBTW, with a CESA, what's the fastest I should swim up? Slower than my smallest bubbles?
Penny for your thoughts.
