(material deleted) This is totally conjecture, but might not the gas scrubber contain not only a C02 absorbant, but also a charcoal cannister? The charcoal (or maybe some other similar material), would absorb organics that might be 'released' by the diver, keeping the suit environment a bit more pleasant. Not sure if the amount of abdominal extension from gas is significant compared to the air space volume in the suit. Good diving, Mike Chalup internet: chalup@pr*.ig*.co*
