Hello Janwillem,
Well I thought I would send you a bit of an update. The info is not real impressive but after creating the MR 101 its first dive was on 23 March 2003, to date I have used it 37 times with a bit over 12 hours of dive time logged. It does have a more compact DSV and all rubber parts are molded, no more cut and glue joints.
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!
