Closed Circuit Rebreather Instructor
for Graduated CCR Supervisors .

Prerequisite: Open Circuit or Closed Circuit Rebreather Divemaster. Must be 21 years of age. Must already own one of the six rebreather models that Ocean Legends International Dive Academy offers instructor, and it must be in safe, working condition.

As closed circuit rebreathers become more popular in the recreational market, there is growing demand for closed circuit rebreather instructors. Closed circuit diving is unique in comparison to open circuit diving because instructors can only teach the specific closed circuit rebreather model they are certified to instruct. Over the course of this 17 week program (or 10 weeks if taking the 40 hr/wk program), consisting of 390 total hours, students will learn how to safely and competently dive their chosen closed circuit rebreather model, and naturally progress in their skills and confidence until they are ready to become closed circuit rebreather instructors in accordance with IANTD standards. Students who have successfully completed Ocean Legends International Diving Academy’s Advanced Recreational Closed Circuit Rebreather Trimix Supervisor Program or students who are open circuit Divemasters who already
own a closed circuit rebreather are eligible to be considered for this program.

Because closed circuit rebreather diving is more dangerous than open circuit diving, Ocean Legends IDA’s standards for the CCR Instructor Program are extremely stringent to ensure only highly competent divers are submitted for certification to IANTD and the rebreather manufacturer. Prospective students should note that they must achieve a score of 95% on every skill and test in the Instructor Development Course in order to be submitted to IANTD and the manufacturer for approval as an instructor. Upon
successful completion of the program, students will receive their CCR Instructor rating and certificate, for their model of rebreather, from IANTD. Students that fail to meet this standard will still receive their IANTD Advanced Nitrox Instructor and Advanced Recreational Trimix Supervisor certifications, and they can received the ratings from IANTD if they pay the required fee to IANTD.
