I've been diving since 1998. I am a PADI MSDT and certified Adv. Trimix and Adv. Gas Blender. I own and operate a shipwreck dive charter on the Great Lakes. For the past 11 years we have been providing charters to Isle Royale in Lake Superior. This year we are doing charters to the south shore of Lake Superior and then on to the north shore of Lake Michigan and the west shore of Lake Huron.
