JJ-CCR Helitrox decompression procedures diver course

Helitrox decompression procedures

This is the next level certification course for divers wishing to utilize a Closed-Circuit Rebreather (CCR) for mixed gas diving, using a Helitrox as diluent.

The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills, to a maximum of 45 metres, using helitrox (air/nitrogen/helium) as diluent for formal decompression diving. Students are permitted to utilize a diluent and bailout mix with percentage of helium not greater than 35% and percentage of oxygen not smaller than 21%.

Who this course is for:

  • The certified TDI Air Diluent Diver (or equivalent) who is looking to extend their depth limitations, learn CCR decompression procedures, and reduce narcosis
  • The open circuit TDI Advanced Nitrox and Decompression Procedures or Helitrox Diver looking to utilize CCR technology to extend their depth limits and bottom times

Course info:

  • Duration: 3-4 days (4 dives)
  • Max depth: 45m
