DISCOUNT for two or more!

The objective of this course is to train already certified CCR no decompression divers or open circuit technical divers in the benefits, hazards and proper procedures for diving the JJ CCR with trimix as a diluent gas to a maximum depth of 40 metres with up to 10 minutes decompression.

Ideally, at this level you should have your own unit, but if you'd prefer we can rent you a JJ-CCR for £100 per day for the duration of your course. 


Skills include:

Decompression planning

Setup and maintenance of the unit

Calibration of electronics

Loop volume management

Buoyancy control

Bailout & emergency procedures

CNS/OTU tracking

In water decompression  



Existing JJ-CCR 30m no deco divers - 

  • 20 logged dives & 20 hours on the unit


Otherwise - 

  • RAID Deco 40 or equivalent

  • 30 open water dives with 20 hours underwater


On course, you’ll utilise specific online Confined and Open Water manuals outlining specific safety skills needed to operate the JJ-CCR enjoyably and safely. RAID rebreather training is unique since it utilises an online training platform to deliver all required academic knowledge backed up with a couple of theory sessions to ensure a firm grasp of knowledge. We'll also conduct a service and repair workshop if you’ve not done one before for dive site maintenance & problem solving.
