What began as a small dive business in 1986 running boat charters out of Bala, Ontario, DeepFathoms emerged as an entity that has continued to support the Canadian diving community for 35 years. With an avid interest in deep shipwrecks, mixed gas and cave diving I sought ways to combine the unique approaches to extended range diving. My company, [doing business at the time as Serious Divers Only (S.D.O.)] expanded taking me across Canada and around the world teaching all levels of diving, operating charter vessels and engaging in a variety of underwater research projects. What came naturally was the evolution of an operation inevitably dedicated to aquatic exploration, specifically marine and diving sciences. This is the story celebrating the 35th anniversary of DeepFathoms.
