The PSAI Advanced Rebreather Diver course builds on your existing CCR knowledge, elevating both your theoretical understanding and practical skills. The course is unit-specific, so you’ll train on the rebreather model you intend to dive with. It blends classroom work with confined water practice and open water dives to reinforce system familiarity, emergency protocols, and dive planning under advanced conditions.
You’ll complete a minimum of six CCR dives during the course, each focusing on specific skill sets:
Throughout the course, divers are expected to demonstrate increasing levels of autonomy and situational awareness. It’s demanding but deeply rewarding training that opens the door to confident, capable rebreather diving in more challenging environments.
Completing the PSAI Advanced Rebreather Diver course qualifies you to conduct deeper and longer dives using a closed circuit rebreather (CCR), typically up to 45 m / 150 ft depending on the unit and your certification path. You'll be equipped to handle more complex dive profiles, including staged decompression and multi-gas planning with trimix or heliox where applicable.
This level of training is often a gateway toward technical diving specialisations such as PSAI Technical Trimix Diver or Expedition-level certifications. It also prepares you for real-world challenges such as extended cave penetrations or wreck exploration, where gas efficiency and redundancy are critical. More importantly, it enhances your ability to plan and execute dives with a strong emphasis on risk management and self-sufficiency.
As always, check with your chosen dive centre—requirements and permitted depths may vary slightly depending on local conditions and instructor qualifications. And don’t forget, you can browse hundreds of advanced diving tours and training opportunities on adventuro!
The PSAI Advanced Rebreather Diver course usually takes 4 to 5 days to complete. This includes a minimum of 6 training dives, classroom theory sessions, equipment workshops, and dive planning exercises. Some centres may extend the course depending on student progress and environmental conditions.
The PSAI Advanced Rebreather Diver course includes both theoretical knowledge reviews and in-water performance evaluations. You'll be assessed on your ability to manage rebreather systems, conduct decompression dives, and respond to emergency scenarios like system failures or bailout procedures. Typical assessments include pre-dive planning, equipment configuration, loop control, buoyancy management, and problem-solving under pressure. Written exams may also be included to test your understanding of physiology, gas management, and rebreather mechanics. While assessment standards can vary slightly between centres, all follow strict PSAI guidelines. Most training culminates in a final qualifying dive where all key skills are demonstrated. You can explore and book training opportunities through adventuro’s extensive listings of PSAI-accredited centres.

Find activitiesA rebreather is a type of scuba system that recycles the diver’s exhaled gas by removing carbon dioxide and adding oxygen as needed. Unlike open-circuit scuba—where exhaled gas is released into the water—rebreathers allow for longer dive times, quieter operation, and more efficient gas use. This makes them ideal for technical and deeper dives, but they require more training and maintenance.
To enrol, you typically need to have completed a PSAI Rebreather Diver course (or equivalent), have logged at least 50 dives, and hold a nitrox certification. Some centres may require documented experience on the specific rebreather unit you'll be using. Always check with your chosen adventuro training provider for exact prerequisites.
PSAI supports training on a wide range of units including the AP Inspiration, JJ-CCR, Hollis Prism 2, and others. Your training will be specific to the unit you choose. Make sure your selected adventuro provider offers instruction on the rebreather model you're planning to use for both training and future dives.
The course usually takes 4–5 days and includes a mix of classroom sessions, confined water skills, and open water dives. Some centres may offer extended schedules for additional practice or specialty unit training. The number of dives typically ranges from 6 to 8, depending on your proficiency and the instructor's assessment.
Yes, PSAI (Professional Scuba Association International) is a respected technical diving agency with global recognition. This certification signals that you have advanced-level competence with rebreathers and is accepted by dive centres and liveaboards around the world. You’ll be able to log decompression rebreather dives once qualified.
You’ll practice key emergency protocols such as oxygen sensor failure, loop floods, and bailout to open circuit. The course also covers dive planning to avoid CNS oxygen toxicity and carbon dioxide buildup. These skills are essential for diving safely with a closed-circuit rebreather and are assessed during open water dives.
While owning your own unit is ideal, many training centres offer rental units for the course. However, familiarity with the specific unit is crucial, so it’s recommended that you train on the unit you intend to use post-certification. adventuro providers list available units and gear rental options on their course pages.
Upon successful completion, you'll be certified to conduct decompression dives using a closed-circuit rebreather within the depth and unit limits covered in your training—typically up to 45–50 metres. You’ll be able to plan and execute extended bottom time dives with appropriate bailout strategies.
Absolutely. The PSAI Advanced Rebreather Diver certification is a stepping stone to more advanced technical diving like trimix or expedition-level diving. It builds essential gas planning, dive execution, and equipment management skills. Many adventuro centres also offer follow-on PSAI trimix and extended range courses.
