Stone Aerospace, in collaboration with DP Scandinavia, is developing the next-generation of recreational and sport diving systems. The fully closed-cycle MK6 rebreather is poised to revolutionize the diving world.

When Cis-Lunar launched it´s MK 5 rebreather back in 1998 it became an instant sensation in the diving community. For the first time ever, a state-of-the art fully automatic breathing apparatus was available for long dives and built with the safety and ruggedness needed for advanced cave exploration and technical diving. And we dare say, no one has yet, nearly 10 years later, matched the performance of the MK V.

The MK5 systems built and sold in 1998 and 1999 are still in use by caretaking owners all over the world and are to this day considered to be the best-in-class device for technical diving (see the schematic advertisement below for some of the revolutionary ideas that were developed for the MK5). The dot.com crash in early 2000 prevented Cis-Lunar from financing mass production of the MK5 and the success story seemed to come to an end.

But now, Cis-Lunar is teaming up with a Swedish industrial group, DP Scandinavia, to develop the long-awaited successor to the MK5 – the recreational MK6 – in additional to other new technologies for the next generation of diving equipment. The joint venture will focus on innovative and high quality diving products, and the commercialization of underwater technology developed by Dr. Stone and his crew of talented engineers. DP Scandinavia, based in Marstrand on the west coast of Sweden, has recruited a seasoned team of manufacturing engineers to develop the methods for mass production of the MK6. In parallel a team of well known and experienced rebreather divers, including Paul Heinerth and Richard Pyle from the USA, Barry Coleman from South Africa, and Hempa Henriksson from the Arctic part of northern Sweden have been brought onboard to support business development, product testing and evaluation.

Dr. Bill Stone (CEO, Stone Aerospace) is recognized as a world authority on expeditionary exploration and advanced technology development with more than 120 engineering publications and 11 patents. In addition to the Cis-Lunar project, he currently leads the development team for the NASA Europa lander third stage prototype known as DEPTHX – a fully autonomous underwater vehicle designed to explore the sub-ice world of Europa and to search for the first microbial life detected off Earth.

“We strongly believe that American ingenuity and Swedish quality is a unique and winning concept. We will jointly develop and launch a series of innovative products aimed for serious recreational and professional divers and are convinced of our competitive edge,” says Dr. Stone.
