TDI JJ-CCR Helitrox
5 days - £795
1 day - £250 (Already qualified CCR Air Dil divers)
Already an open circuit technical diver?This course is similar to the JJ-CCR decompression procedures course but because of your experience will allow you to dive using a diluent and bailout gas mix of no greater than 20% helium and no less than 21% oxygen. The qualification depth is still 45 metres but the diver will be trained to use air/nitrox & helium diluent for decompression diving, yet further extending bottom time and significantly cutting the effects of gas narcosis.
Alternatively, you might want this course as a one day bolt-on if you already hold the JJ-CCR Deco Procedures course.
Skills include:
Setup and maintenance of the unit
Loop volume management
Calibration of electronics
Emergency procedures
Buoyancy control
CNS tracking
Decompression planning

What’s next
Once you have completed a minimum of 50 CCR dives totalling at least 50 hours (25 hours minimum on the JJ-CCR) you can progress to the TDI CCR Mixed Gas course (MOD2/Level 2). The course is designed to use trimix as a diluent and bailout gas to safely conduct decompression diving to a maximum depth of 60 metres.
