Marius, we never dive narcotic mixes , and of course we set the oxygen to the max depth of the dive. You have to balance out the risks here: on the surface, you do not breathe your gas, you breathe the air, and you drop down a few feet immediately when you do breathe the bottom gas. If you have a problem, you either hold at a breathable depth or go back to the surface and come off the reg while dealing with it. Travel is great in a cave where you have some distance to cover and floor that corresponds to the breathable depth. You can stop, switch, get ready , and then go. This is actually more to save the bottom gas in case there is a problem and you have to restart the dive, so that you have only used a little travel ( deco ) gas, not part of a stage. We still are not using narcotic or hyperoxic mixes, we are using the correct trimix, and we are taking a couple of minutes on the switch. There is no hurry in these cases. -----Original Message----- From: Marius Svanevik [mailto:Marius.Svanevik@st*.ui*.no*] Sent: Thursday, May 31, 2001 4:36 AM To: Trey Cc: Techdiver@Aquanaut.Com Subject: RE: Trimix Computers At 21:14 29.05.01 -0400, Trey wrote: >By the way, "travel" gases must be used carefully, and only where they fit: >it takes about two minutes for the effect of the last gas to wear off, so if >you are dropping, you are still "on" that mix well after you do not want to >be. > >JT is right on the money with this bailout thing. Are you "on" the mix for just nitrogen narcosis, or for oxtox as well? Marius -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
