lets see ... math ...
my lungs are big, so 1 cu ft per min per ATA divided into a 13 cu ft pony equals 13 mins at the surface, 6.5 mins at 33 fsw, 3.25 mins at 100 fsw, 2 mins at 150 fsw.
granted he better move fast, ditch the wt belt &/or integrated wts, exhale into the B/C, kick up, then once buoyancy takes over, start dumping B/C air and flare for the arrival at the surface, and then call 9-1-1 the minute he is back on the beach.
thats still a happier ending than it really was: no air, no buoyancy, no buddy.
