Hypoxic Trimix CCR

The Hypoxic Trimix CCR course is the highest level certification course for divers wishing to utilize the unit specific closed circuit rebreather (CCR) for advanced mixed gas diving. The objective of the course is to train divers in the benefits, hazards, and proper procedures for advanced mixed gas diving on a CCR and to develop advanced CCR diving skills appropriate to technical diving to a maximum depth of 100 metres / 330 feet (or shallower if mandated by local law).

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, have a Cave CCR rating and a Cave DPV rating. If students wish to take the course in the ocean, destination travel can be arranged.  

Certification is through TDI, IANTD, NSS-CDS.
