Is it expensive to own and dive a rebreather?
That depends on the type of diver you are. With all the benefits and features of a rebreather, professional divers find the MK 15 (at a price of about $10,000) invaluable. With the introduction of the Dräger Dolphin and Ray rebreathers, recreational divers can enjoy most of the same benefits and features of a professional type of RB unit for a cost of about $3500.00.
