I decided to start building a semi-closed rebreather in the spring of 2003, however, my first SCR prototype leaked like a Swiss submarine. I knew that I had to find a different way to connect the hoses to my breathing bag. Today I use the MSR breathing bags, standard p-connector from Dräger, Dräger Ray canister or our own canister which is developped here in Sweden, on the east coast.We use standard Ray hoses, standard first stages (Apeks and Poseidon) and second stages, standard 3 liter bottles (CE approved), Apex OP valve, standard LP and HP hoses, etc. All my parts except for the Dräger parts are standard products found on the regular scuba market. All of the parts used in my design can be bought on the webb. The only parts that I have designed myself are the breathing bag design, T-connector, the special adapters to the canister, and off course: our canister. The backplate and bladder are from Halcyon and Dive Rite (Can´t we all live in peace?) ;=).
