Phi - if you get near anything you should reach back and check the
knobs on your tanks right then and there whether the gas has been cut
off or not. It it not so much rolling one off that is a problem with
hitting the ceiling of a cave or wreck, it is BREAKING one of that is
the real problem. You need to know this right away. Also, the inflator
holds enough gas to allow a hit or two without knowing it is off, so you
still have not received the information you need. Get near objects,
check knobs. When there is a problem, like rolling one off and/or
breaking it, you still have a backup if your inflator is on the other
post. That one may break off, but it will not roll off .

   Additionally , the more hoses that cross behind your neck, the better
chance you have of hearing a reg that is creeping or freeflowing. This
is more true in deep water than in shallow.

   Again, the inflator needs to be long enough that you can 1) breath it
easily, 2) hold it in your hand while clearing your ears by holding your
nose, and 3) hold it in your hand and operate it while simulatanously
operating the drysuit inflator.

    DIN manifolds with ports on the outside are relatively new to this
sport ( as in the last ten years). Most players had the old center post
manifolds, and turned off the long hose when staging to prevent losing
gas - a bad practice. I use a lower perfomance or detuned reg out there
to prevent this instead, and I keep my intermediate pressures low .

    We were the first to really get into DIN arrangements, in fact I was
the first in the WKPP to do so,  and the logic I use to arive at these
configuartions will stand the test of anyone's argument. Also, I only
deal in the real world. I do not teach diving ( other than certain parts
of complicated courses for other instructors - in the classroom only
((rule number one))), and see no need to accomodate anything that will
not be used for any level of diving. That is the way I go it.
