The JJ-CCR Rebreather: Your Ultimate Underwater Companion for Technical Diving Adventures
The JJ-CCR rebreather is renowned as the “4 x 4 of the rebreather community,” a fitting description for a diving apparatus that excels in diverse underwater environments and caters to the needs of the most demanding technical divers. This rebreather was purposefully designed and engineered by professional wreck divers, primarily for exploring the deep, dark, and cold waters of the Baltic Sea. As such, it offers a robust and simple construction, making it ideal for handling various challenging situations.
Here at Tech Dive Asia we have JJ-CCR units for rent, Cylinders for hire, Scrubber and a good selection of spare parts.We have experienced JJ-CCR instructors and dive guides to make your diving in Thailand an unforgettable adventure.
One of the key strengths of the JJ-CCR lies in its adaptability and versatility, making it suitable for a wide range of dives. We dive the JJ on some of our deeper offshore reefs and wrecks and also in the caves of Thailand.
The philosophy behind the JJ-CCR revolves around keeping it straightforward, reliable, and easy to handle, both before and after the dive. The main assembly comprises a durable aluminum housing and a stainless steel stand that holds essential components such as counter lungs, wings, and harness. This design ensures comfort on land while donning the rebreather and provides stability during underwater exploration. Additionally, the JJ-CCR features optimized hoses and gas paths for superior performance in water and simplified maintenance.
To cater to the needs of experienced technical divers, the JJ-CCR comes equipped with state-of-the-art electronics, including a digital HUD (Head Up Display) that provides real-time PPO2 (partial pressure of oxygen) readings from all three oxygen sensors. Moreover, a reliable controller with an integrated Shearwater multi-gas decompression computer ensures a safe and efficient diving experience.
For experienced technical divers the familiarity of the Shearwater computer makes learning to dive the the JJ-CCR so much easier than propitiatory dive controllers.
Key Features of the JJ-CCR Rebreather:
- Highly Robust Aluminum Housing: The rebreather’s rugged aluminum housing can securely accommodate up to four diving tanks (ranging from 2 to 12 liters) using conventional tank belts, ensuring a steady and balanced configuration during dives.
- User-Repackable Soda Lime Canister: With an axial design, the JJ-CCR offers the convenience of repacking the soda lime canister, minimizing downtime between dives.
- Heavy Duty Stand: The stainless steel stand provides stability and support, allowing divers to handle the rebreather with ease, both on land and underwater.
- Integrated Handle: An integrated handle enhances portability, simplifying transportation and preparation for diving.
- Back-Mounted (Over the Shoulder) Counter Lungs: This positioning of counter lungs offers optimal breathing performance and streamlining while diving.
- Redundant Power Supply: The rebreather includes separate batteries for the controller, HUD, and solenoid, ensuring backup power for essential systems and enhancing safety.
- Integrated ADV (Automatic Diluent Valve): The ADV automatically maintains the appropriate gas mix in the loop, contributing to a smooth diving experience.
- DSV (Dive Surface Valve): The DSV facilitates easy control and management of the rebreather’s functions during the dive.
- Manual Oxygen and Diluent Supply Valves: These valves allow divers to introduce external gases if needed, offering flexibility and adaptability in different scenarios.
The JJ-CCR rebreather is a user-friendly, robust, and versatile diving apparatus designed to exceed the expectations of demanding technical divers. Its simplicity and adaptability make it suitable for skilled divers who seek a silent and seamless diving experience.
