TDI Air Diluent CCR Decompression Procedures Diver – rEvo Rebreather Training

The TDI Air Diluent Closed Circuit Rebreather Decompression Procedures Diver Course expands on the skills learned in the entry-level CCR program and introduces divers to planned decompression diving using a closed-circuit rebreather.

This course is conducted using the rEvo Closed Circuit Rebreather, a highly reliable CCR system known for its dual scrubber design, efficient gas management, and robust construction.

During this course, divers learn how to safely plan and conduct staged decompression dives while using a rebreather system. Training focuses on advanced dive planning, gas management, decompression theory, and disciplined team procedures.

Students will develop strong control of buoyancy, trim, and propulsion while managing multiple gases and decompression obligations during CCR dives.

Training dives are conducted to a maximum depth of approximately 40 m / 130 ft, using air as the diluent gas, while performing staged decompression procedures according to TDI training standards. 

This course prepares divers for more advanced rebreather programs such as:

• TDI Mixed Gas CCR Diver

• TDI CCR Cave Diver programs
