COUNTERLUNGS
These are made from the PVC backed nylon I mentioned. Easy to glue and sew, I will see how long they last!
The lungs sit inside
4" PVC tube which is open to the water. The tubes afford the lungs some
protection and are also used to mount the tanks. The C/Ls are kept as close to
my body as possible.
The right photo
shows the Draeger dosing head off a RAY which pierces the PVC and enters
the (inhale) C/L via a P connector, so it can easily be detached. Gas is
supplied from the diluent bottle which also feed a bailout 2nd stage and gas for
the wing and drysuit. The Draeger manifold distrubutes this nicely, although
I've still got a way to go with hose routing. The dosing head has been modified
by changing the sealing tube to one off a Dolphin. This gets rid of the
constant dosing feature and makes it a demand only valve, ie an ADV.
