How can you put a fourth cell for info on a deco computer?
Dave Pelly sent me these pictures about fitting a fourth cell for your VR3
Here is my method of connecting 4th cell. I have obtained an undrilled cell holder from APD and drilled four cell positions staggering alternate cells vertically to fit them in. The lid has been drilled and a Fischer connecter fitted . The VR3 is connected by using a cable with a Fischer connector on each end. I did this to primarily eliminate the cell holder tee piece which has proved troublesome ( leaky !). An added bonus is that the VR3 now seems to track more consistently with the handsets

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!
