SF2 eCCR Air Diluent


For the more demanding diver, the entry-level rebreather course for the SF2 eCCR system is available at Koh Tao Tech Divers.

In this course, you will learn about the benefits, hazards, and proper procedures for rebreather diving on this specific system. Moreover, you'll learn the basic eCCR dive skills you will need to the max. depth of 30 meters / 100 ft while using air as the diluent. No decompression diving during this course!

The TDI Air Diluent Rebreather course runs over five days. Should you wish to continue on to decompression procedures on CCR, the course takes seven days if you meet the prerequisites.

We highly recommend purchasing and owning your rebreather. However, we understand you might wish to try the system out before purchasing your own unit. It is possible to rent the rebreather when needed to use on your course.

All our courses are conducted by experienced technical diving instructors and instructor trainers.
