JJ-CCR MOD2 course

Mod 2 course on the JJ-CCR

The JJ-CCR MOD 2 course is an intermediate certification program for divers aiming to use CCR’s for mixed gas diving. This training focuses on developing your understanding of the benefits, risks, and correct procedures for conducting mixed gas dives on the JJ-CCR.

Throughout the course, you will gain the skills needed to safely dive to depths of up to 60 metres using helium-based diluent gases containing at least 16% oxygen. The program builds your competence in advanced gas management, dive planning, and emergency protocols essential for technical diving at greater depth


Diving to greater depths demands advanced knowledge of gas management and thorough dive planning – and that’s exactly what the TDI MOD 2 CCR Diver course delivers. This training prepares you to plan and execute CCR dives to 60 metres, incorporating at least two or more stage cylinders.

Throughout the course, you will deepen your understanding of your rebreather system and learn how to effectively manage and recover from various potential failures. You will also consolidate your core CCR skills while refining your gas planning and dive planning abilities.

This is the certification level many divers aspire to when they begin CCR diving. By the end of the course, you will have the confidence and competence to safely enjoy dives to these depths, fully equipped with advanced skills for mixed gas diving.

TDI MOD 2 Mixed Gas Instructor

Our primary instructor for the TDI Mixed Gas course on the JJ-CCR is Kevin Black. With over 20 years of experience on rebreathers and as a Rebreather Instructor Trainer with multiple training agencies Kevin brings a wealth of knowledge on deep rebreather dives. He can be found regularly on the local dive boats doing longer, deeper dives and has a range of locations perfect for 60m dives where very few other divers have seen. Be sure to book a few extra days of diving after the course to explore some of his favourite sites.

All Kevins MOD2 Mixed Gas courses are taught 1 on 1 with a focus on mentorship developing your current skill level with the unit to explorer level. The course includes an element of servicing and repair to keep you going in the field and useful knowledge gained from diving a wide selection of rebreathers.

Kevin hopes you will join him exploring some of these technical dive sites and helping discover new technical dive sites. Kevin has the largest supply of helium and sofnolime in Phuket and has pre mixed trimix bail out gases ready to go. Some of these sites are best done with DPV so if you are not already qualified it is worth combining DPV Training with your course.

Kevin is the only JJ-CCR factory approved Level 2 Instructor on the west coast of Thailand. Kevin teaches Mixed Gas courses every month. Check our course schedule for the next available course or contact us below for specific dates.

Courses can be completed on our rental units or your own unit and even on the JJ-CCR XRC
