Simplicity and versatility are the key factors

The JJ-CCR is built for whatever dive you have in mind.
The JJ-CCR Rebreather is designed and built to exceed the expectations of demanding technical divers, but the simplicity of the machine makes it ideal for any skilled diver that wants to go silent! The JJ-CCR Rebreather has been called "the 4 x 4 of the Rebreather community" which is in many ways a consistent description as it is built for all types of terrain and can be adapted to handle the most demanding adventures.

Quick brief about the JJ-CCR

The JJ-CCR rebreather is built to be user friendly, robust, versatile and adaptable to whatever dive you have in mind! It is ready to fly right out of the box, but build as a platform simple to adapt in numerous configurations depending on your skills and needs. All components of the JJ-CCR rebreather has a purpose and every detail can be justified. It has industry low work of breathing, state of the art electronics with redundant power supply, a user friendly design and heavy duty construction. A slim, robust and simple construction opens for the diver to place bailout, light canister, or gas for bouyancy needs directly on the scrubber housing.

The birth of the JJ-CCR

Everything started some years ago when I did a rebreather course with Jan Jorgensen. After that I decided to buy a rebreather, but Jan Jorgensen said to me: This is not an option for you - you can build your own rebreather! He already had a design of a new rebreather in his mind.

After that we spent a lot of time together and I showed him what would be possible to machine. The very first prototype of the JJ-CCR Rebreather was ready for diving in March 2006. Jan Jorgenson was one of the "crash test dummies" - Already after the first dive he really liked the unit very well and he was surprised about how good everything worked. I also spend many hours with test diving the rebreather and try to improve the overall design and features.

In January 2007 we got the first Shearwater GF. Lars Steffeesen - a good friend - did a try dive with it. We never got back the rebreather! Another unit was send to Dave Thompson to do some try dives and play around with it. Dave Thompson had designed some backmounted counterlungs he wanted to try with the JJ-CCR Rebreather. We never got back this unit either! Again I had a lot of work in drawing and machine the parts for the unit. And again a lot of test dives with a small group of Danish friends. I was lucky enough to meet Henrik Søgren and he helped me with some design issues and machining. 3 Years later in March 2009 the JJ-CCR Rebreather was finally ready for the official testing at Quinetiq in England. The first testing was done in June 2009 and with a huge success the unit passed all the tests toward the EN14143 standard.
