Since some of these pictures were taken I have changed the isolator valve to
point straight back away from me. It is easier to reach the slightly longer
distance round the pillars than to slide a gloved hand with a computer on the
wrist etc. between my back and the first stages.
Is it easy to set up? Look at the pictures.
Lay the tanks down with the bolts pointing up. The picture shows the Custom
Divers tank protectors (Bull bars) on which the rig stands while you put it
on. I also use screw in DIN valve protectors to keep the threads clean but I
remove them totally and put them in the toolbox once the regs are fitted as
they will either get lost, get entangled in something or, more likely, end up
under the Bull Bars when I sit back down and get trashed.
Fit the regs and route the hoses. On the left (near side) is the primary reg,
a longer than normal wing inflator running up between the tanks and a
Scubapro SPG and depth gauge console. On the right the secondary reg feeds up
between the tanks while the drysuit inflator and a second SPG are clipped
together. The two SPGs end up clipped to the chest D-rings so they are quick
and easy to see but the drysuit hose is only there to stop it getting lost
and is unclipped as I put the rig on and I fit it to the Apeks swivelling
Lay on the wing ensuring the two hoses are safely in the gap between the
tanks so the backplate will trap them without pinching them. The DiveRite
Classic, purchased without the harness, is very simple and tough as old
boots. It has a fabric panel virtually the width of the backplate so it is
unsuitable for a single cylinder rig but pretty much ideal for the twinset.
I have kept the pull to dump that is hated by the purists as it is, I feel, a
useful feature. The inflator will be passed through a bungie loop on the left
chest D-ring to keep it in an obvious grab zone.
Then the backplate is fitted which is always rigged with the harness. Again I
depart from the pure Hogarthian rig by fitting a pinch clip to the crotch
strap. This makes dekitting to get back into a RIB much easier as I can let
go the clip and hand off my weight belt more easily. Finally fit and gently
hand tighten the wing nuts and stand the set up on the valve protector and
put it on. I can now turn on the gas, check the isolator is open about three
quarters of a turn.
