Closed Circuit Rebreather (CCR) Diving Trips & Guided Dives
CCR Diving (Closed-Circuit Rebreather) – No Bubbles. No Limits.
At Extreme Watersports, CCR diving is not just a course — it’s a complete system built around precision, confidence, and true underwater freedom. Whether you want longer bottom times, smoother decompression, or quiet wreck exploration, CCR opens the next level of diving when done correctly.

Closed-Circuit Rebreather (CCR) Guided Dives & Courses
Closed-circuit rebreather (CCR) diving represents the highest level of efficiency, control, and flexibility in modern scuba diving. By recycling breathing gas and maintaining a controlled oxygen partial pressure, CCR diving allows for extended bottom times, optimized decompression, reduced gas logistics, and access to advanced dive profiles when conducted with proper training and discipline.
At Extreme Watersports, CCR diving is approached as a structured system, combining formal CCR training courses with guided rebreather dives that allow certified divers to gain experience in a controlled, fully supported environment.
CCR Training on the Dive Rite O₂ptima CM (PADI & TDI)
All CCR courses at Extreme Watersports are conducted on the Dive Rite O₂ptima CM, a proven, modular, and widely used closed-circuit rebreather platform. The O₂ptima CM is known for its robust design, manual control capability, travel-friendly configuration, and suitability for both training and advanced CCR diving.
We provide CCR certification through both PADI and TDI, allowing divers to choose the agency that best aligns with their certification background and long-term CCR progression. Regardless of agency, training standards focus on competence, discipline, and repeatable execution, not minimum timeframes.
CCR courses emphasize:
- Rebreather system knowledge and setup
- Loop management and breathing control
- PPO₂ monitoring and control
- Bailout planning and execution
- Failure recognition and response
- Controlled ascents and decompression on CCR
Training follows a progressive pathway, allowing divers to move from entry-level CCR certification to more advanced CCR diving as experience and confidence develop.
Guided CCR Dives – Experience with Full Technical Support
CCR guided dives are offered for certified rebreather divers who want to build experience, consolidate skills, or maintain proficiency while diving with full operational support. These dives are not instructional courses; they are experience-focused dives conducted with structured planning, clear objectives, and disciplined procedures.
Each guided CCR dive includes:
- Structured dive planning and briefings
- Gas planning and bailout verification
- Team assignments and procedures
- Controlled ascent and decompression execution
- Post-dive debriefs for performance review
Guided CCR dives are ideal after certification, before advanced CCR training, or as preparation for expedition-level diving.
Full CCR Support & Gas Services
Extreme Watersports provides complete CCR diving support, allowing rebreather divers to focus on dive execution rather than logistics. We support divers using all major CCR units, not only the Dive Rite O₂ptima CM.
CCR support services include:
- Rebreather cylinders (oxygen and diluent)
- Sofnolime / CO₂ absorbent
- Diluent and bailout gases
- Decompression gases
- Nitrox, Oxygen, and Trimix blending
- Gas analysis and verification
- Stage and decompression cylinder support
Multiple gas mixes and bailout options are available to support a wide range of CCR dive profiles, from no-decompression CCR dives to advanced decompression and technical CCR dives.
Local & Expedition-Level CCR Diving
CCR guided dives and courses are conducted in environments suitable for rebreather diving objectives, allowing divers to apply skills in real-world conditions. Experience building may take place locally, while advanced CCR dives and expedition-level projects are supported through structured planning and logistics.
International CCR dive trips and expeditions are organized with the same operational standards, including:
- Full mixed-gas support
- CCR consumables and spares planning
- Dive planning and contingency management
- Expedition-level procedures and safety systems
Who CCR Guided Dives & Courses Are For
CCR guided dives and courses are suitable for divers who:
- Want formal rebreather diving certification
- Are interested in guided CCR dives after certification
- Want longer bottom times and optimized decompression
- Value structured procedures and disciplined execution
- Prefer full technical and gas support
- Are preparing for advanced CCR or expedition diving
CCR diving rewards divers who value planning, precision, and system understanding over shortcuts.
Certification, Progression & Ongoing Experience
CCR certification confirms that a diver has met the required training standard on a specific rebreather platform. Continued experience through guided CCR dives is strongly recommended to reinforce skills, maintain proficiency, and build confidence before progressing to more advanced CCR training.
Progression in CCR diving is based on demonstrated competence, not minimum dive counts.

Closed-Circuit Rebreather (CCR) Diving – Frequently Asked Questions FAQs
Closed-circuit rebreather (CCR) diving is a form of scuba diving that recycles breathing gas and maintains a controlled oxygen partial pressure (PPO₂), allowing divers to achieve longer bottom times, optimized decompression, and efficient gas usage compared to open-circuit diving.
CCR diving offers extended bottom time, reduced gas consumption, optimized decompression profiles, quieter diving, and greater flexibility for advanced and technical dive planning when conducted with proper training and discipline.
Yes. CCR diving requires formal rebreather training and certification. Divers must complete a recognized CCR course before using a rebreather independently due to the complexity of the equipment and procedures involved.
All CCR courses at Extreme Watersports are conducted on the Dive Rite O₂ptima CM, a widely used and proven closed-circuit rebreather suitable for training, technical CCR diving, and expedition-level dives.
We provide CCR certification through both PADI and TDI, allowing divers to choose the rebreather training agency that best fits their certification background and long-term CCR diving goals.
Yes. CCR guided dives are available for certified rebreather divers who want to gain experience, consolidate skills, or dive with full operational support in a structured environment.
We provide full CCR diving support, including rebreather tanks, Sofnolime (CO₂ absorbent), diluent gases, bailout gases, and decompression gases, as well as gas analysis and dive planning support.
Yes. While CCR training is conducted on the Dive Rite O₂ptima CM, guided CCR dives support divers using all major rebreather systems, provided they meet safety and compatibility requirements.
We provide Nitrox, Oxygen, Trimix, diluent, and decompression gases to support a wide range of CCR dive profiles, from entry-level CCR dives to advanced technical CCR diving.
CCR diving is suitable for experienced recreational divers who meet entry requirements and complete formal CCR training. It is not intended as a replacement for basic recreational diving but as a progression into advanced diving.
CCR diving is safe when conducted with proper training, disciplined procedures, redundant planning, and continuous monitoring. Like all advanced diving, it requires respect for procedures and equipment limitations.
The duration of CCR training depends on the course level, diver experience, and skill development. Progression is based on demonstrated competence rather than fixed timelines.
No. Equipment requirements are discussed during course planning. Divers may complete CCR training using provided or rental equipment before deciding to purchase a unit.
Yes. CCR courses are structured to allow progression into deeper, longer, and more complex CCR dives as experience, certification level, and competence increase.
CCR courses and guided CCR dives are conducted in environments appropriate to the dive objectives, including local CCR diving and international CCR expeditions with full technical support.
The first step is to speak with a CCR instructor to review your experience, certification level, and goals. This ensures the correct CCR course or guided rebreather dive pathway is selected.
