Project background
I decided to start
building a semi-closed rebreather in the spring of 2003, however, my first SCR prototype leaked alot.
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 and/or
APs counterlungs and loop, 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, the
"SS fischbone adapter" for the backplate and off course: our canister. The backplate and bladder are
from Halcyon and Dive Rite (Can´t we all live in peace?) ;=).
The
idea is to recycle as much divegear as possible from the conventional scuba market and convert it to a "safe",
fun & diveable rebreather unit, that is my goal.
The
Hunchback has been manually tested down to 32 meters (soon it will be tested to 60 meters!!) in the field and
it works exellent. It is easy to swim with, perfect trim in the water, and easy to breath.
This project
is alive and kicking! We have carried out several imrovements during 2006. I have continued developing some new ideas around
the Hunchback concept, but version 8.0 is now the active version and is under intensive testing by me. I am adding new
information about this version on my blogg all time now during 2009. Please follow the blogg for more updated information
around the trials and my personal thoughts around the project and version 8.0.
