CCR Training

It's time. You have drunk the Kool-Aid. You have succumbed to the urge to join the Dark Side. You want to join the popular kids. There are a lot of terms for it, but in short, you want to dive a rebreather. Whether you're a photographer who is sick of frightening the fish, or an experienced diver that has encountered the limits of open circuit for certain dives,  or you just want to look as good as all of your friends...welcome. 


The first step in your new trajectory as a CCR diver is the MOD 1 class. This certifies you to conduct no-decompression dives using air as a diluent to depths not exceeding 100 feet. Instruction is available on the APECS 2.7, Meg 15, and Pathfinder. Your class will take at least five days, during which you will learn:

  • History and evolution of rebreathers

  • Comparison of open circuit (OC), closed circuit, and semi-closed circuit, rebreather (SCR) systems noting the pros and cons of each

  • Gas physiology

  • Practical mechanics of the system: unit assembly, disassembly, care, and troubleshooting

  • Dive planning and execution

  • Emergency procedures


To enroll for this course, you must be at least 18 years old; have proof of 20 logged dives; and have a nitrox certification from a recognised agency. Given the advanced nature of this course, however, we strongly suggest that students possess advanced nitrox and decompression procedures training and experience.

Air Diluent Decompression Procedures

After several months of CCR diving experience, (or at least 30 hours), qualified divers may wish to conduct decompression dives to 130 feet using air as a diluent. In this course, you will acquire more in-depth knowledge about:

  • Pros and cons of conducting decompression dives using OC, SCR, and CCR systems

  • Gas physiology

  • Dive planning and execution

  • Emergency procedures

Given the specialised nature of rebreather diving, we can't recommend highly enough that you acquire your own unit. Please contact us ahead of your class for assistance.
