Rb Pages
The pSCR  must be used from start with
a switchblock that allows feeding the rb
injectors with a variety of mixes that
could increase bottom time and enhance
decompression exposure.

The switchblock goes on the right side of
the diver clip to the chest "D" ring. The
idea is to protect from undesire impacts
and debri. Also is a must to be able to
visually monitor its function at all times.

On first clasess gue promote hide it on
the left side under the butt monitoring by
feel, now they are using it on the right but
stil experimenting where to clip it from
wing to light "D" ring.

The original switchblock comes from the
fridge has some features are no really
need it anymore as the OPV, Over
Pressure Valve, as in the early days
stages regulators were rig with just the
"rb plug" in the drive bottle 1st stages.
This is very stupid and not done
anymore. We put two hoses one with rb
and one with OC 2nd stage, which
means you can use the stage bottle both
as rb or in OC

Another disadvatage is size, weight and
needed custom hoses.

New manufacturers been listening and
reducing the failure point of multiple
conections also reducing the size of it
some examples on the right.

Is nice to be able to have standard
hoses instead of custom, but is
desirable the filters on hose plug in.

99% of the rb industry uses sliding shut
off they are smaller and don't get close
by accident or snag on cable, hoses or
cave line.
