A very early electronic closed circuit rebreather
The Biomarine CCR1000 is the civilian version of the Biomarine MK15. The Yellow sportsdiving rebreather was tested by NEDU in 1975. The unit itself was designed in 1969! Richard Larn wrote this article in Underwater World magazine.

Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
