Imagine sliding through the water, accompanied not by the roar of bubbles, but by silence. Imagine getting close and personal with aquatic life – getting closer than ever before. When you dive with a semiclosed rebreather, you’re nearly bubble free – reducing the noise and disturbance that can scare away shy creatures.
Through either the Semiclosed Rebreather Draeger Dolphin/Atlantis Specialty course or the Semiclosed Rebreather Draeger Ray Specialty course you learn the special procedures for semiclosed rebreather diving. This includes special dive planning, organization, procedures and potential hazards, many of which differ significantly from conventional (open circuit) scuba.
