Purpose The mCCR Rebreather Diver 1 is the first step to becoming a certified rebreather diver. This course is designed to educate individuals in basic rebreather technologies and cultivate diver proficiency in the use of fully closed-circuit manual technology and how to apply it to their recreational diving needs. The mCCR Rebreather Diver 1 course assumes that individuals are capable divers who are experienced with single stage/deco bottle diving, but have no experience in the use of rebreather technology. This course will cover using a fully closed rebreather in recreational diving depths within no decompression limits. Prerequisites Must be a minimum age of 21 years of age. Must have completed the online UTD mCCR Rebreather classroom and test Must have UTD Tech 1 or equivalent. Must have a minimum of 125 dives. Must be able to swim a distance of at least 60 feet/18 meters on a breath hold. Must be able to swim at least 300 yards/275 meters in less than 12 minutes without stopping. Course Limits Student to Instructor ratio is not to exceed 4:1 during any in-water training. Maximum depth 130 feet / 39 meters. No Decompression Limits (NDL) Course Content The mCCR Rebreather Diver 1 course is normally conducted over a 7-day period, and cumulatively involves a minimum of 60 hours of instruction designed to provide a working knowledge of rebreather diving, including history, design, function, failures, tables, and operational considerations. Course requirements include a minimum of ten hours of academic review and 4 pool dives (4 hours or 240 mins) and ten rebreather dives (10 hours or 600 mins) , of which eight are critical skills dives and two are experience dives.

Understand and develop skills to master the priority assignment philosophy Demonstrate the ability to perform the Pre Dive Setup and calibrate the unit at least five times. Demonstrate proficiency with going to and from Closed Circuit to Open Circuit Demonstrate the ability to recognize, evaluate and correct any gas addition interruptions and/or failures, then terminating or continuing the dive as necessary. Demonstrate the ability to recognize, evaluate and correct water intrusion, and what to do to remove excess water. Demonstrate excellent buoyancy control skills. Procedures for gas failures; including valve manipulation, air-sharing, and regulator switching as appropriate. Demonstrate the effective diagnosis and correct response to simulated rebreather problems Lift bag/surface marker buoy deployment. Be able to comfortably demonstrate at least two propulsion techniques that would be appropriate in delicate and/or silty environments. Air-sharing scenarios for at least 200 feet/60 meters Demonstrate effective valve-management by switching regulators, shutting down a valve and returning the valve to the open position. Demonstrate water tight integrity of the unit by performing a vacuum and pressure test (Pre Dive Check) Demonstrate the capacity to efficiently supply gas to an out of air diver. Demonstrate the ability to efficiently manage gas addition systems with either hand. Demonstrate efficient ability to perform 2 loop recoveries. Demonstrate proficiency with Toxing Diver rescue. Demonstrate proficiency with maintaining a constant PPO2 within 0.2 of the instructor discretion Demonstrate comfort with CC Equipment Requirements Rebreather: mCCR fully-closed circuit rebreather Tanks/Cylinders: Students are required to use dual tanks/cylinders connected with a dual outlet isolator manifold, which allows for the use of two first stages. The double cylinders must be accessible by both the rebreather and the open circuit regulators. A single oxygen decompression bottle/bailout with a single first stage and a second stage. All dives must start with a minimum of 40cf/1120 liters of gas in backgas/bailout. Regulators: Two first-stages, each supplying a single second stage. One of the second stages must be on a 7 foot/2 meter hose. One of the first stages must supply a pressure gauge and provide inflation for a dry suit (where applicable). One oxygen supply/bailout decompression bottle with appropriate regulator. Buoyancy Compensator: Back-mounted wing, mated with a harness and back plate At least one depth-measuring device One timekeeping device Mask and fins: fins must be of non-split variety At least one cutting device Underwater slate or Wet Notes One reel/spool, with 75 feet/22 meters of line, per diver One primary reel per team, with a minimum of 300 feet/90 meters of line Two lights: one primary and one secondary Exposure suit appropriate for the duration of exposure At least one surface marker buoy per diver
