Semiclosed Rebreather Course - Dolphin or Ray
Diving with a semiclosed rebreather is fantastic. Your buoyancy doesn't change by breathing. Also you create almost no bubbles, so fish are more curious and come to see you.
This course is designed to introduce you to the Dräger Dolphin or Dräger Ray semiclosed rebreather and to develop your knowledge, skills and techniques necessary to use these types of rebreathers.
The course reviews the planning, organisation, procedures, potential problems and hazards associated with semiclosed rebreather diving. It specifically focuses on the features, accessories, maintenance and proper use of the Dolphin or Ray semiclosed rebreather.
