Michel Biesmans Le Joky MCCR

Michel Biesmans send me pictures about his manual controlled rebreather “Le Joky”.

Michel sent me pictures of his Manual controlled Closed Circuit rebreather. On the pictures you can also see a sidemount rebreather with a special loop worn on one side, used a lot in the cavediving world. Have fun studying the configuration!

Michel Biesmans Joky ECCR 007 — Les deux petits boîtiers marqués par du scotch de couleur ne sont pas des afficheurs mais servent d’adaptateurs entre les connectiques du VR3/rEvodream et la tête où se trouvent les cellules. En passant, on notera les protections de robinet.
The two small boxes marked with colored tape are not displays but serve as adapters between the VR3/rEvodream connectors and the head where the cells are located. By the way, notice the tap protections.

Michel, thank you for contributing to this section of the homebuilders!

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!
