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

Hello All,
In an ambient sub, of course you have to deal with physiological effects of breathing pressurized gasses but that is identical with being a scuba diver who must religously follow the dive tables.I know divers who dive alone and who
also dive decompression dives with mixed gasses and they just keep dialing up the risk.In general, the deeper you go in your sub,ambient or 1atm the greater risk your taking. I have been 940 feet in my sub maximum,at this depth or even less nobody can resue me (In Michigan) in time eventhough I carry mabee 36 to 48 hours supply of O2 and soda zorb.I certainly cannot evacuate the sub at these depths.From what I understand approx 450 feet is the record for the maximum actual ascend from a crippled sub.(can anyone verify this?)

THE DEEPER YOU GO THE MORE RISK YOU ARE TAKING! in ambient or 1atm
