The TDI JJ Closed Circuit Rebreather (CCR) Air Diluent Diver Course is your first step into closed circuit rebreather diving and your first truly quiet dive experience! Using the latest technology in CCRs can maximize your gas supply and provide an optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen. It’s like having a nitrox blending machine on your back! During this course, your TDI Instructor will teach you all the necessary skills to conduct no decompression CCR dives to a maximum depth of 30 metres/100 feet using air diluent.

The JJ CCR is a rugged and versatile rebreather developed for harsh wreck and cave environments. It has been called ‘the 4 x 4 of the rebreather community, which in many ways is the perfect description as it is built for all types of terrain and can be adapted to handle the most demanding adventures. There are many different CCRs on the market, but we firmly believe JJ CCR is one of the best! The JJ CCR is known for its robust construction, user-friendly design, and versatility. It is often used by technical divers who engage in deep or extended dives, where conventional open-circuit scuba diving equipment may be insufficient.

As with any diving equipment, it is essential to receive proper training and certification before using the JJ CCR or any rebreather system. Diving with a rebreather requires additional knowledge and skills beyond open-circuit scuba diving due to the different gas management and potential risks associated with closed-circuit systems.
