These numbers are subjective due to the fact that there was a lack of funds to support a full blown experiment (if I remember correctly, U.S. Navy studies support these numbers, the SEALS use argon on extended underwater missions). As I eluded to in my previous post, how well you purge your suit at he beginning of the dive will determine the increase in thermal effectiveness. Another issue that effects the insulation quality is how much you have sweat, more moisture = greater theraml conductivity. During a typical sport dry suit dive, the diver will sweat upto a 1/4 liter and this will condense out in the suit potentially causing cold spots. I would expect this measure to be greater during a hardcore cave dive. > > Jay Jeffries - how much does argon increase the effectiveness >of thinsulate? -George > > =====================================================================Oo==== I Capt.
