Re: [PSUBS-MAILIST] a 1atm dry sub or a potential coffin?

Carsten,
   You are absolutely right. I really feel that anyone
working or playing underwater should be a qualified
diver unless they just want to walk the undersea
aquarium tunnels at Sea World. Something as seemingly
simple as escaping a sub at 25 ft can be VERY lethal
if you do not know how to do it right. Can anyone say
Arterial Gas Embolism? Any good diver can. Play safe.
