CCR Normoxic Trimix Supervisor .

Prerequisites: Must be at least 21 years of age. Must be an IANTD Advanced Recreational CCR Trimix Supervisor or a closed circuit rebreather instructor.

This 396 hour, 18 week program (or 10 week program if taking the 40 hr/wk option) is for students who want to lead closed circuit rebreather customers on dives up to 200 feet. Dives at these greater depths open up new terrain and less explored dive sites, but it also requires greater responsibility and training to lead divers safely to this depth. This program will give students the confidence and skills necessary to be a successful and competent dive supervisor at dive locations around the world. To enroll in this program, students must already have one of the six closed circuit rebreather models that Ocean Legends International Diving Academy requires in its other programs. Upon successful completion of this program, students will receive their IANTD CCR Normoxic Trimix Supervisor certificate and their Normoxic Trimix Supervisor certificate from the rebreather manufacturer.
