You have got to be kidding me, first off, no one has the ability to drag me up by my regs,
I just report what I saw while diving Duane. It has NOTHING to do with you.
a quick jerk on the hose and it's free,
IMHO, anyone in the profession such as lifeguard, swim instructor, dive instructor, coastguard... that involve possible drowning victims will be humble and have high respect of the strength of drowning victims to grap on anything as their life depend on it. Especially those that have had experience with saving panic drowning victims before, will know, any kind of quick jerk would not free anything from a panic victim. Please don't take my word for it, go talk to oldtimers in the lifeguard profession...
Spare Air, you have got to be kidding, I'd rather my buddy drag me to the surface from the deck of the Duane then run out of air at 80 ft.
Again, no kidding. I am just sharing real life experience. I have saved 3 lives with spare air. For them, their families, and myself, we were grateful that I had my Spare Air with me.
A diver gets panic when he suck H2O instead of air. A few breath of air from a little Spare Air bottle gave him a Chance to calm don't a little bit a put make the situation a little more manageable. Every little positive improvement in an emergency situation increase the chance of survival.
Sorry, I can't find any way to explain it better for you. It is difficult for you to understand unless you have witness a real life situation.
