For those that dive a system with zero ditch-able weight....... like a BP/W and plate, and are not diving a drysuit...... what happens if you have a total BC or Wing failure at the surface? Maybe DSMB or SMB? Something else?
I can swim with 2 10-lb bricks and my gear weights about 10 lbs. Well, plus the tank. So yeah, something else: I'll have to kick a little harder.
