| | "Be that as it may, SCUBA divers have long known that a blast from the tank first thing in the morning does wonders in blowing away the fog.".. uh.. no scuba diver I know dives with tanks of pure oxygen; oxygen is *highly* toxic to humans under high pressure, and therefore useless to scuba divers (unless they're diving in such a shallow depth at which to render tanks unnecessary).
Scuba divers dive with tanks of *air* - even Nitrox divers (nitrox diving requires a lot more training than vanilla scuba diving) only dive with a 32 to 36% Oxygen breathing mixture.
