Well we finally did it. We made our own semi-closed circuit pendulm rebreather. The breather itself is made from parts from our primary supplier, Home Depot and Lowes. Cost of the breather was under $100.00 excluding the cylinder and regulator. More pics can be viewed at www.airheadsscuba.com/pendulum.html
We designed it as a bailout system primarily for cave. A 40 cf supply cylinder can increase our pentration based on time and not depth / time as is the case with OC bailout.
