The objective of this course is to train already certified CCR no decompression divers in the benefits, hazards and proper procedures for diving the JJ CCR with air/nitrox as a diluent gas to a maximum depth of 40 metres with up to 15 minutes decompression.

Skills include:

Decompression planning

Setup and maintenance of the unit

Calibration of electronics

Loop volume management

Buoyancy control

Bailout & emergency procedures

In water decompression               


RAID’s ethos regarding the JJ-CCR is that this unit is a technical rebreather and therefore for this course you’ll need to:

Minimum age 18.

Hold a CCR no decompression certification.

Minimum of 10 hours on CCR within last 18 months & logged at least 5 hours between deeper than 20m.

Knowledge Development             

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.
