Cold water divers, if they are silly enough not to use a separate drysuit inflation source, will definitely notice that they get really cold really fast breathing on helium and using it to inflate their drysuits because of how fast it conducts heat away from the body. Incidentally, I tried this once a number of months later while assisting Gideon as videographer in a drysuit Tech1 class in Izu, Japan—hey, you have to say you’ve tried it ONCE just so you know from experience… But that was in 23 degree (Celsius) water only to 45 meters for a few minutes. I can’t even imagine doing it in colder water or for the entire 30-minute bottom time. Brrrr…..I was frozen. But in the waters of the Philippine we had no such concerns!

This reminded me to my Tech-1 and failure of argon tank regulator on day four (no replacement). It was exactly two years ago (late March), the water tempreture was 9 to 10 degrees Celsius and it was even colder outside (and raining in addition). "Frozen" was not enough strong word to describe my condition.
