Helitrox CCR Deco Procedures Diver
This is the second entry-level certification course for divers who wish to use a closed-circuit rebreather (CCR) for mixed-gas dives using Helitrox as a diluent. The objective of this course is to introduce divers to the benefits, hazards, and proper procedures for diving with a CCR and to develop basic CCR diving skills, up to a maximum depth of 45 meters / 150 feet, using an air/nitrox/helium diluent for formal decompression diving. Students are authorized to use a blend of diluent and backfill with a helium content not exceeding 35% (+/- 5%) and an oxygen content not less than 21%. Students are authorized to use up to 100% oxygen for decompression.
- Duration: 5 days
