Hi

Maybe you are interested in my D5 mods. I have some pictures of it in my
album on a Swedish diveforum:

As I think you run it I also found that a std Ray-DSV is nicer for
slingoperation.

I have changed to inhale and exhale bags. O2 is feed from a KISS valve
mounted on the sling O2-cylinder. I detuned a RAY-dosage so that it does
not open to easy (no dil CMF-flow) and use it in the inhale bag as an ADV.

There are also two cells in the inhale bag. I run an rEVOdream with HUD
from it.

I put in a spring loaded one way valve downstream of the BCD-conector in
the bag for the O2 so that it can be disconnected UW without flooding.

I also exchanged the purge valve in the scrubber for a OPV from my RAY.
And added a strip of lead sheet to the bottom of the scrubber to balance
it.

I must say I'm very pleased with how this thing works. With a good
KISS-flow and the HUD and ADV I really do not need to bother much about
operating the unit while diving. ADV-injection and OPV-dumping makes very
distinct noises so I notice it easily.

As you can see I'm no sidemount diver and I believe in carrying lots of
bailout. But since the D5-is so slimmed swimming around inside wrecks is
no trouble even with a twinset on the back and another sling O2-cylinder.

For me the bag volume is almost perfect, slightly above minimum loop
volume so the unit does not change much in boyancy during diving. And its
easy to go heads up or down trough openings.

So have you started on some new sling rebrethers?

I'm working on having the cells in the top of the scrubber and to make
stripping the unit faster. A fancy thing I just noticed the other day is
that an extendair cartridge fits nicely inside the rocket tube with an
about 6-7 mm airgap around it...

Exhale down around the outside of the cartridge and inhale trough the
cartridge. Making a solid holder directing the gas around it could be a
nice thing. If the ever start selling those things for a reasonable price
here in Europe.
