I have made an online master diver quiz and I had a question in there that sparked a conversation over on scubatoys board. Here is the situation how I learned it: You have surfaced (safely), a bit later a diver pops to the surface in distress, you tell him ot inflate his bc, etc... he won't or can't do it. So I was taught to extend flotation...fully inflate your bc, take it off (rescuers gear is expendable) -> float it over to the victim in distress. The discussion came along when someone said if someone comes towards them on the surface they would want to submerge below him...my question, why not swim away? Looking for different points of view...
