PADI Rebreather Diver Course | Closed-Circuit Rebreather Certification

The PADI Rebreather Diver Course is the entry-level certification for divers who want to begin closed-circuit rebreather (CCR) diving under controlled depth and operational limits. This course introduces divers to the fundamentals of rebreather diving, focusing on safe operation, disciplined procedures, and system awareness rather than relying on automation alone.

At Extreme Watersports, the PADI Rebreather Diver Course is conducted on the Dive Rite O₂ptima CM, a proven and widely used closed-circuit rebreather suitable for training and progression into advanced CCR diving.

What Is the PADI Rebreather Diver Course?

The PADI Rebreather Diver Course trains divers to safely use a Type R (recreational) or Type T (technical) closed-circuit rebreather within no-decompression limits or limited decompression (as permitted by unit classification and standards). The course emphasizes proper preparation, loop management, PPO₂ awareness, bailout planning, and emergency response.

This certification allows divers to conduct CCR dives within the limits of the training received, using the specific rebreather unit they were trained on.

Course Objectives

By the end of the PADI Rebreather Diver Course, divers will be able to:

• Assemble and configure the rebreather correctly

• Conduct complete pre-dive checks and setup procedures

• Monitor and manage PPO₂ during the dive

• Maintain correct loop volume and breathing control

• Plan CCR dives within course limits

• Execute safe ascents and decompression (as applicable)

• Respond correctly to common CCR malfunctions and failures

• Plan and execute bailout procedures

Course Structure

The PADI Rebreather Diver Course consists of:

Knowledge Development

• CCR theory and system overview

• Oxygen management and PPO₂ control

• CO₂ considerations and scrubber management

• Failure modes and emergency procedures

• Dive planning and rebreather-specific risk management

Confined Water Training

• Loop management and breathing techniques

• PPO₂ monitoring and manual control skills

• Bailout drills and emergency responses

• Unit handling and buoyancy control

Open Water Dives

• Practical CCR dive planning and execution

• Controlled descent, bottom phase, and ascent

• Task loading and situational awareness

• Real-world application of CCR procedures
