JJ-CCR Training & Sales

A Robust Platform for Technical Exploration

The JJ-CCR is a back-mounted electronic closed-circuit rebreather developed around robust construction, straightforward operation and a high level of redundancy. Blue Water Ascent is an Authorised Dealer providing unit-specific TDI training in Melbourne and supplying JJ-CCR units, parts and spares. Whether you are choosing your first CCR, completing a unit crossover or progressing into decompression training, we connect equipment selection with disciplined procedures and deliberate in-water coaching.

Training Pathways

Who JJ-CCR Training and Equipment Are For

The JJ-CCR pathway suits divers selecting their first CCR, qualified JJ-CCR divers progressing into planned decompression or helitrox diluent diving, and experienced CCR divers completing a unit crossover. It also supports divers seeking a robust platform for longer-term technical, wreck or overhead-environment objectives. The right starting point depends on your qualifications, recent experience and intended diving.

Prerequisites and Readiness

The minimum age is 18. Entry-level Air Diluent candidates must hold Nitrox certification or equivalent and provide evidence of at least 20 logged open-water dives. Decompression-level pathways require the qualifying technical or CCR certifications and experience specified by current TDI standards. All prerequisites and recent experience are verified before enrolment.

How the Training Works

Training combines academic development, equipment maintenance and configuration, confined-water practice and progressive open-water dives. Under the supplied TDI standards, the full Air Diluent, Air Diluent Decompression Procedures and Helitrox pathways each require at least 60 minutes of confined-water work, 420 minutes in open water over a minimum of seven dives, and a minimum five-day course. Crossovers and upgrades have level-specific requirements. Your programme is confirmed against current TDI and JJ-CCR requirements and progresses only when control, awareness and judgement are repeatable.

Skills Developed on the JJ-CCR

You will develop unit assembly and care, scrubber preparation in accordance with manufacturer instructions, pre-dive checks, oxygen-sensor calibration and monitoring, breathing-loop and volume control, buoyancy and trim, setpoint awareness, bailout planning, team communication and disciplined responses to unit-specific failures.

Certification and Diving Limits

Air Diluent certification permits no-decompression JJ-CCR diving to a maximum of 30 metres. Air Diluent Decompression Procedures extends unit-specific training to planned decompression diving to 40 metres. Helitrox Diluent Decompression Procedures introduces a helium-containing diluent and formal decompression to 45 metres within current TDI gas limits. Training dives may be shallower or more conservative according to conditions and demonstrated readiness.

Unit Crossovers

JJ-CCR crossovers are available for appropriately certified CCR divers with suitable recent experience. The programme focuses on the JJ-CCR configuration, assembly, electronics, loop characteristics, preparation, monitoring, emergency procedures and bailout strategy. Exact academic and in-water requirements are confirmed against certification level, logged experience and current TDI and JJ-CCR requirements.

JJ-CCR Equipment, Training and Ongoing Development

As an Authorised Dealer, Blue Water Ascent can assist with the purchase of a JJ-CCR and connect equipment selection with unit-specific training. The JJ-CCR uses a robust aluminium housing, back-mounted counterlungs, an independent head-up display, a Shearwater-based controller and separate key power supplies. Selected equipment, parts and spares are stocked locally, while other products are supplied to order. We begin with your intended diving, current qualifications and longer-term objectives, then discuss an appropriate unit configuration and realistic training pathway. Availability, configuration and lead times are confirmed individually.
