Closed-Circuit Rebreather Training & Certification – PADI & TDI

Extreme Watersports offers closed-circuit rebreather (CCR) courses for divers seeking proper rebreather training, disciplined procedures, and internationally recognized certification. Our CCR courses focus on system understanding, loop management, PPO₂ control, bailout planning, and controlled execution rather than reliance on automation.

All CCR training is conducted on the Dive Rite O₂ptima CM, a proven and widely used rebreather platform suitable for both recreational and technical CCR progression.

CCR certifications available through PADI and TDI.

Closed-circuit rebreather diving allows divers to recycle breathing gas, maintain a controlled oxygen partial pressure, and significantly extend bottom time while optimizing decompression. When combined with proper training and disciplined procedures, CCR diving offers exceptional efficiency and flexibility for a wide range of dive profiles.

CCR diving is not defined by equipment alone. Safe rebreather diving requires:

• Formal CCR training and certification
• A strong understanding of the rebreather system
• Continuous PPO₂ monitoring and control
• Effective bailout planning
• Precise buoyancy and ascent discipline

CCR Training Philosophy

At Extreme Watersports, CCR courses follow a structured progression, starting with discovery and entry-level programs and advancing into technical CCR diving. Training emphasizes:

• Manual and electronic PPO₂ control
• Loop volume management and breathing discipline
• Failure recognition and response
• Bailout execution and redundancy
• Standardized CCR procedures

Progression is based on demonstrated competence, not minimum timeframes.

Training Platform – Dive Rite O₂ptima CM

All CCR courses are conducted on the Dive Rite O₂ptima CM, selected for its:

• Manual and electronic control capability
• Robust, modular design
• Travel-friendly configuration
• Compatibility with both PADI and TDI CCR pathways
• Suitability for recreational, technical, and expedition CCR diving

Training on the O₂ptima CM provides a strong foundation for long-term CCR progression.

PADI & TDI CCR Certification Pathways

Extreme Watersports provides CCR certification through both PADI and TDI, allowing divers to choose the training agency that best aligns with their background and future objectives.

PADI CCR courses focus on:

• Progressive recreational to technical CCR development
• Clear performance standards
• International recognition

TDI CCR courses focus on:

• Technical CCR progression
• Decompression and mixed-gas CCR diving
• Advanced technical application

Our instructors will advise on the most suitable pathway based on your experience and goals.

Who CCR Courses Are For

Closed-circuit rebreather courses are suitable for divers who:

• Want longer bottom times and efficient decompression
• Are interested in advanced or technical diving
• Prefer structured procedures and disciplined execution
• Want formal rebreather diving certification
• Plan to progress into technical or expedition CCR diving

CCR diving rewards divers who value planning, precision, and system understanding.

Equipment & Support

CCR training includes full operational support, including:

• Rebreather cylinders (oxygen and diluent)
• Sofnolime / CO₂ absorbent
• Diluent and bailout gases
• Decompression gases
• Nitrox, Oxygen, and Trimix blending
• Gas analysis and verification

This allows students to focus on learning and execution rather than logistics.

Not Sure Which CCR Course to Start With?

Choosing the correct CCR course is important. Entry points depend on:

• Current certification level
• Logged dive experience
• Long-term diving objectives

We recommend speaking with a CCR instructor before enrolling.
