TDI CCR Helitrox Decompression Procedures JJCCR or XCCR

Advance your CCR diving with TDI CCR Helitrox decompression course

Designed as the second-level certification course for divers seeking to explore mixed gas diving using a Closed Circuit Rebreather (CCR) with a Helitrox Diluent, the TDI CCR Helitrox Decompression Procedures Course offers comprehensive training in the benefits, hazards, and proper procedures associated with CCR diving. This course aims to equip divers with essential skills for conducting formal decompression dives to a maximum depth of 45 meters/150 feet, utilizing an air/nitrox/helium diluent. Students will be allowed to use a diluent and bailout mix containing no more than 35% helium and no less than 21% oxygen, with the option to use up to 100% oxygen for decompression.

Who this course is for:

• Certified TDI Air Diluent Diver (or equivalent) seeking to expand their depth limitations, learn CCR decompression procedures, and reduce narcosis.
• Open circuit TDI Advanced Nitrox and Decompression Procedures or Helitrox Diver interested in leveraging CCR technology to extend depth limits and bottom times.

What you can expect to learn:

The TDI Diving Rebreathers Student Manual and the manufacturer’s manual are essential resources during this course. The curriculum covers a wide array of topics, including:

• History and evolution of rebreathers
• Comparative analysis of rebreather systems
• Practical mechanics of the CCR system
• Gas physiology fundamentals
• Dive planning strategies and emergency procedures

Required skill performance and graduation requirements:

Students must meet all standards set by both TDI and the rebreather manufacturer, ensuring adherence to maximum limits. Key open water skills include:

• Executing open water dives within specified depth ranges
• Conducting safety stops
• Demonstrating proficiency in equipment assembly and emergency procedures

What’s in it for you?

Upon successful completion of the course, graduates gain the ability to engage in decompression diving activities utilizing a CCR independently, within predefined limits. Additionally, graduates are qualified to enroll in advanced courses such as TDI Mixed Gas CCR unit-specific courses and the TDI Advanced Wreck Course.
