Hi Ingemar, what you said in your last email, makes sense to me! Looks like lot of people don't know what coldwater-diving is like. Anyway, one should not overvalue the advantage of Argon along with a Trilaminate drysuit. For me personal, while diving almost strictly in cold water environments (temperature around 34-50°F), the combination of a 9mm compressed neopren dry-suit plus a electrical heated undersuit along with several layers of thinsulate underwear, plus dry gloves is the first choice. The use of Argon only makes sense, if you completely flood your suit before your dive, to ensure, that absolutely no air is left in the suit. You do flooding, when you inflate your suit with Argon 1-2 times and deflate again, so the much denser gas Argon has pushed out the air inside of your suit. With this outfit, I had no problem, diving under the pack-ice of the North-Polar circle, going down for 350ft with dive-time of 100+ minutes. Besides that, I do dives almost every weekend in cold-water lakes (approx. 40°F) and do dives in the 450-550ft range with dive-times of 80-140 minutes without having any thermo-problems. The Typhoon XCM-heated undersuit along with Argon suit inflation works great than. Mario Ingemar Lundgren schrieb: > The TLS works fine for cold water.
