Helitrox CCR

The Helitrox CCR course is the second entry level certification course for divers wishing to utilize a closed circuit rebreather (CCR) for mixed gas diving using a Helitrox 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 / 150 feet, using an air/nitrox/helium diluent for formal decompression diving. Student are permitted to utilize a diluent and bailout mix with no greater than a 35% helium content (+/- 5%) and no less than a 21% oxygen content and are permitted to use up to 100% oxygen for decompression.

Please note: Because the only north-Florida dive sites which offer the necessary depth for this training, you must be certified to the Full Cave Diver level. If students wish to take the course in the ocean, destination travel can be arranged.
