I took one of the first GUE Rb classes in the
90's and was told to put switchblock in the left
and other nonsense including wrong theoretical
Po2 drops. Trey came to mexico to my dive
center and give me some pointers thru diving
with him in 1999, later when diving rb in the
EKPP in 2001 I figure out a few more things.
There are two main currents on hose
configuration, for mono Rebreather, both name
after developing teams. Also there is a double
rb configuration.
UTD / EKPP configuration is the simplest most
streamlined. Basically you ad to the back up
reg the rb mouthpiece, as if the shock cord
become the rb hoses. Then also ad a bailout
drive hose to the left post. So 5 hoses 2 second
stages one rb mouth piece. Suitable to
configure with non swivel diaphragm 1st stages.
Rb mouthpiece back up reg comes form left
post and point to the left post. Hoses configure
nicely straight down leaving the knob free and
reducing hose crowding behind neck.
Most used configuration worldwide and in
Europe and what I make standard in al rb
courses in UTD and my IANTD courses.
WKPP configuration ads a hose to the right
post so mouthpiece back up reg points right,
as well bailout drive hose is on the left. So 6
hoses 3 second stages.
For its nature is difficult to configure with
diaphragm reg so usually is done with piston.
This is used in modern wkpp and a hand full of
some of the certified gue divers, main
reasoning is the low reliability on mouthpiece
bailout. As the second stage diaphragm on the
traditional rb mouthpiece is not UW screwable,
in fact has seven screws, so when diaphragm
dislogde can not be adjusted in the water.
As well is not a balanced second stage so
breath poorly at depth.
The new Golem BOV solves all this problems,
while increasing field of view, new model shrimp
is also light and smaller !

Configuration
History
Redundant RB diving was introduce
by solo divers or small weak teams
without capable set up divers.
The rb80 due its size could be back
mounted, a heavy guy for sure.
However is been the choice when
there is no possibility of bringing
enough OC bailout gas for the
team, or if dives ever get beyond
12hr bottom time, (excluding deco),
however are seldom need it.
An extra deco rb in addition of a
mono rb set up for bottom time is
pretty standard, and usually side
mount mounted. This is an area to
develope in the future, efficient deco
rb's.
