Rb configuration should start with a solid
frame, the frame is intended not only to
carry bailout gas but also, primarily to
protect rb Integrity
The smallest bottle for OW diving is 8.5lt /
65ft3 (same bailout of 18'lts/125ft3 at
100bar) for cave training build up should be
12Lt or al80's, the later are easier to start
setting up the rb and getting use to the
procedures in land also are lighter,
therefore an option for wet suit diving and in
rare remote extremely deep and cold wreck
diving activities.
Up the ladder and into what the rb was built
for talking about long range cave diving,
double 20Lt is the prefer choice.
Double manifold isolation is a must in all
cases, but specially in single back gas
bailout and/or single stage dives.
The center connection, should be fixed
steel pipe. Notice the swagelok one is a
"use and change" seal system.
In special situations, I use custom thread
isolation valves that allows to remove/
change tanks from frame without empty
them, for expedition transportation where
carrying the whole frame as unit is not
possible IE. Sumps, jungle, horse, etc.
Benefits of using the standard frame in
CCR allows to fit a larger sofnolime canister
and you do not have to remove back plate
and wings to remove rb.
As no frame is well design for CRR rb's I
decide to use my pSCR frames and it
works, however will be designing a new
one, shortly.
To use this EKPP frame with a CCR need
the harness, set up on pictures below
Also i used last winter in Mexico a Halcyon
frame in picture below.
I mount this unit for OW diving on the new double 8.5lt tanks,
equivalent to 3750lt or 125ft3 of OC bailout, in other words same as
leaving the bottom with 100bar/1500psi with double 18lt /125's tanks.
In the pictures on the left you can see travel frame is not really an
advantage for expedition rb diving
In my experience travel frame and similar are the worst choice and not
an option on the long run, in fact should be avoided for cave diving.
Single tank adapters frames jeopardize rb integrity and therefore
catastrophic failure, the rb was not designed to carry any weight.
Common problems with expose rb frames is rb damage or failure upon
un-desire impacts.
Let alone a HUGE pain in the butt to set it up EVERY time!
Hopefully soon we can develop a DIR rb frame that can accept either
pSCR and CCR units, for those interested in diving one configuration
and just choosing rb efficiency upon mission.
