Upside-down on the left side and as low as possible to keep them in the slipstream of the doubles to reduce drag. It has to be in a position where you can reach the valve and remove the bottle completely if necessary. Some may argue that placing a pony that way should be OK since it's OK for an argon bottle. The problem with that logic is that argon bottles are different from ponies; they're smaller (too small to be very useful for breathing) and they're *necessary* in cold/long dives, which ponies are not. -Mike Rodriguez <mikey@mi*.ne*> http://www.mikey.net/aue Pn(x) = (1/(2^n)n!)[d/dx]^n(x^2 - 1)^n -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
