BSAC’s CCR Diver (40m) training is your first step into the silent world of rebreather diving. It’s a great way to learn the basics about closed-circuit rebreathers.
I had been considering moving to rebreather diving for some time, and after completing this course I wish I had done it sooner! It’s a solid introduction to CCR and has opened up a whole new route of bubble-free, reduced deco diving that I will continue to explore.

The CCR Diver (40m) course teaches a qualified open-circuit diver to dive either an AP Diving rebreather – Evolution, Evolution+ or Inspiration – or a Poseidon Se7en. You will get a thorough grounding in rebreather technology, alongside unit-specific training, and learn how to adapt your existing diving skills to a new world where you benefit from always breathing an optimum gas mix.
To enrol on the CCR Diver (40m) course you must have successfully completed a BSAC Sports Diver course with 35-metre depth certification, and have at least 50 logged dives. You also need to be an Accelerated Decompression Diver or Advanced Nitrox Diver (or have equivalent certification from another recognised training agency).
You’ll learn to safely dive a closed-circuit rebreather to a maximum of 40 metres using air diluent, including carrying out decompression and gas planning. You’ll develop your practical CCR diving techniques and get to grips with how to respond to kit failure.
The CCR Diver (40m) course includes nine theory sessions covering physics, physiology, dive conduct and potential kit problems, and two dry practical sessions on preparing and maintaining your rebreather. There is a sheltered-water training dive to introduce new skills. Then you’ll spend at least 360 minutes on a minimum of six open-water dives, to ensure that you have plenty of in-water time to practise the skills and discipline needed for CCR diving.
This is a continually assessed course during which students must reach the required standards.
A BSAC CCR Diver (40m) is competent to plan and conduct CCR dives, including those with mandatory decompression, using an AP Diving or Poseidon Se7en rebreather with air as the diluent gas. You will be able to progressively build up to dive to a maximum depth of 40m, which allows many people to do the majority of the diving that they want to. You will also be able to rescue another CCR diver from depth.
You could do this course at a regional event, local club or a Technical centre. Not all clubs and technical centres run CCR Diver (40m) courses, so please check if you are interested.
Alternatively, book your place on a scheduled Regional CCR Diver (40m) course online now.
Not a BSAC member? You can do this course by joining BSAC directly or joining via a local club. Find a club.
Students will be given a pack of supporting learning materials. You will need full open-water dive kit suitable for local conditions and the relevant rebreather. You will also need a fully kitted stage cylinder to use as an independent alternate source.
Your next steps – developing your skills
After completing a CCR Diver (40m) course and consolidating your skills, your options for club diving significantly expands.
- You could progress to Sport Mixed Gas CCR Diver (50m) and enjoy the benefits of reduced gas density and narcosis that using trimix as a diluent brings, bringing greater comfort and enjoyment at extended depths of up to 50m.
- You could develop specific skills to expand your diving interests further, including technical and logistical courses such as Explorer Mixed Gas CCR Diver (60m), Advanced Mixed Gas CCR Diver (80m), Compressor Operation and Mixed Gas Blender. Check out the Skill Development Courses (SDCs) you can get involved in.
- You could sign up for BSAC’s Instructor Foundation Course (IFC) to start your instructing journey with BSAC.
- Already an Open Water Instructor? You could develop your existing skills to become a Technical Instructor.
