in Canada the diving never stops................
I throw on a pair of viking 400s, charge up the argon bottle (major insulator factor). 6mm neoprene Abyss drysuit, my nordic blue dry gloves, an Ice cap. I use a Mares Abyss 22 with an cold water kit, (best breathing reg under any conditions). This past January I spent 70 minutes submerged under the ice, dress as discribed, came out toasty warm. The previous year on one occasion I spent a total of 4 hours mostly in the water, had to pee bad but I was warm...............got to learn not to drink that large coffee before diving...............(hee hee)
diving is a year round sport........................no doubt
hmmmmm 2mm suit in Canada at the best of times would produce major shrinkage factor................
