Tek-course: The Semi-closed Circuit Rebreather Diver

The Semi-closed Circuit Rebreather Diver course will provide you with the skills and knowledge you need to minimize the risks of using Semi-closed Circuit Rebreathers (SCR) to a maximum depth of 100 fsw / 30 msw and while using Nitrox mixtures of 32% to 80% oxygen.

Your training will include analyzation of breathing gas mixtures; buoyancy control skills; scuba diver rescue simulation to including management of a diver experiencing underwater convulsions, hypoxia, flooded system, and out of breathing gas scenarios; training in redundant breathing gas systems; proper counter lung flush procedures; and ascent with a line reel and lift bag while simulating a required decompression stop. Additional topics covered in your course include proper post dive procedures, physics and physiology, equipment; review of dive tables including RGBM tables, narcosis depth, dive planning requirements and gas management planning.

Semi-closed Circuit Rebreathers used for NAUI certification courses must have been independently tested before training on a specific model can be authorized.
