Even with a very low helium content in the bottom mix the temperature loss will be significant. Helium transfers heat much more rapidly than air (roughly 5 times). It's a better to get some argon from your buddy. > I was trying to > save bottom mix but it's probably not worth it. I have done many dives solely using the drysuit for bouyancy control and it came out that for typical V or square profiles (no jojo) I never used more than 8cuft inflation gas (with ~4cuft being the average). So if you now compare the price difference between 4cuft bottom mix and 4cuft argon you will find it's realy neglectable! Forget that and stick to clean hose routing. Reality check: Asume you dive to 300'. We are carrying double 104, 2*80 and 30 stages (~400cuft gas volume total). When we are weighted propper the worst case is that we must compensate the negative bouyancy at the beginning of the dive at 300' to remain neutral at the surface when all gas is breathed off. 400cuft air weights around 30lbs. To create 30lbs lift at 300' we must have to inflate the wing/drysuit so that the volume is increased by roughly 13 litres this means we would require ~5cuft inflation gas. Regards, Frank P.S. Of course we dont dive air but it's reasonable heavy -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
