Description
TDI CCR Mixed Gas Diver
The TDI CCR Mixed Gas course is your next step into closed circuit rebreather diving, with the addition of helium as a diluent gas. The objective of the course is to train divers in the benefits, hazards and proper procedures for CCR mixed gas diving, and to develop skills suitable for CCR technical diving to a maximum of 60m.
Who this course is for?
- The certified TDI Air Diluent Decompression or Helitrox Diluent Decompression Diver (or equivalent) looking to extend their depth limitations.
Course Prerequisites
- Minimum age 18
- Provide a verified log of a minimum of 50 rebreather hours distributed over a minimum of 50 dives on the specific rebreather. If the diver has 50 hours on another CCR unit recognized by TDI, only 25 hours are required to be on the specific unit
- Have completed and qualified the TDI Air Diluent Decompression Procedures Rebreather/TDI CCR Helitrox Diluent Decompression Procedures Diver course or equivalent from agencies recognized by TDI
