PSAI Advanced Rebreather Diver is the step after sport rebreather training when you want staged decompression on a semi-closed or closed circuit unit. You work with nitrox pre-mix or air diluent, manage oxygen in the loop, and build the bailout discipline that keeps rebreather incidents from becoming headlines.
Most programmes run over several days with theory, equipment workshops and open water CCR dives. When the Advanced Nitrox component is taught, PSAI qualifies decompression diving to a maximum of 45 metres. A non-decompression path exists that upgrades Sport Rebreather qualification to 40 metres only. Your depth rating follows your experience, unit and instructor assessment, not your enthusiasm on the briefing board.
This is not mixed-gas trimix CCR training. That sits in Fundamentals Mixed Gas CCR Diver after you have the advanced rebreather foundation. Arrive with recent time on your unit, honest loop checks and patience for repetitive drills. Rebreather skills feel fussy until they are automatic, which is the point.
PSAI Advanced Rebreather Diver is assessed through theory and in-water performance on your qualified unit. Your instructor signs off when decompression and emergency skills meet PSAI standards.

Find activitiesIt is PSAI's advanced rebreather rating for staged decompression on SCR or CCR with nitrox pre-mix or air diluent. With the decompression and Advanced Nitrox component, qualification reaches 45 metres.
A separate non-decompression path upgrades Sport Rebreather to 40 metres only. Your instructor confirms which track you are on before serious open water weeks begin.
PSAI Sport Rebreather Diver or equivalent on the unit you will dive, plus the decompression foundation your centre requires for the deco track. Substantial logged rebreather time is expected.
Leave a comment when you book with your unit model, dive count and certification cards. Cross-agency equivalency is common but never assumed without verification.
With the decompression and Advanced Nitrox component, PSAI qualifies advanced rebreather diving to 45 metres. The non-decompression sport upgrade path caps at 40 metres.
Depth rating is commensurate with experience, unit and instructor assessment. Mixed gas trimix CCR to 60 metres sits in Fundamentals Mixed Gas CCR, not this course.
Yes. Rebreather certifications are tied to the SCR or CCR model you train on. Switching units later requires additional training on the new hardware.
Confirm your centre teaches your unit before you pay a deposit. Manufacturer service intervals and configuration standards still apply after certification.
Typically a multi-day programme with theory, workshops and open water CCR dives. Centres vary on dive count and whether confined water sessions are included.
Gas logistics, scrubber supply and weather slip schedules regularly on rebreather courses. Build slack into travel plans.
A rebreather recycles exhaled gas, removes carbon dioxide and adds oxygen to maintain a breathable loop. You get longer bottom times and quieter diving, but new failure modes appear quickly if checks are lazy.
Hypoxia, hyperoxia and hypercapnia demand constant monitoring. The course builds habits your open circuit training never needed.
Your centre specifies bailout cylinder size, gas type and mounting for the unit and depths on your course track. Planning assumes you can reach the surface or deco gas on open circuit if the loop fails.
Undersized bailout is a common student mistake. Ask for the centre kit list early and budget for extra cylinders and fills.
No. This course uses nitrox pre-mix or air diluent for decompression rebreather diving within PSAI advanced limits. Trimix diluent and 60 metre mixed gas CCR training is Fundamentals Rebreather Diver (60m).
Think of Advanced Rebreather as the deco foundation on your unit before you add helium diluent and expedition depth.
That is reasonable. Deco on a loop adds task loading to stops you already respect on open circuit. Instructors drill bailout and setpoint management until responses are boring.
Leave a comment when you book if you want extra shallow practice or a slower progression. Rushing rebreather training is how people learn expensive lessons.
Beyond course fees, budget for sorb, oxygen and diluent fills, bailout cylinders, servicing and spare O-rings. Rebreather diving is not a cheap hobby once you own the unit.
Many students rent units for training before committing to purchase. Ask the centre about rental, consumables and manufacturer service requirements.
adventuro lists PSAI centres running Advanced Rebreather programmes where unit-specific instruction and gas support exist. Compare bailout policies, sorb supply and whether confined water is included.
Train where you can get repetitive dives on your unit after certification. One week of drills does not make you a seasoned rebreather diver.
