    There might be a way of designing the complete system and actually
getting the thing to breathe in a pool, but the minute you start to swim
with it you will see that it doesn't belong in a cave. The first thing I see
as being a problem  is the number of bottles needed to supply each unit-or-
the complicated plumbing wrapped around the diver to allow for multiple
feeds.

    If there was a way of compacting the units and making the breathing
hoses deployable in a neat and quick way, then you would find the buoyancy a
big problem for caving. I'm sure you would dive dry, so now you have four
expanding air spaces that you would have to dump or leave full and counter
weight them. For caving this would be a clusterfuck.

    Now try this with a scooter, dude, it ain't gonna happen. I am thinking
of Manatee Springs and the way you can fly through there with a dry suit and
bc inflator in constant operation.

    I am sure Ted busted your balls during the cave class, but nothing
really prepares you for the crap that can happen in a real Murphy
experience. This system would have to be an ingenious display of the art of
gear configuration in order to make self rescue a viable option.

    Keep trying to make this a reality. You will probably come up with a few
tricks that I can use to get my breathers in a better position to be used in
a cave. I am still working on getting these ready,but I will definitely keep
things as simple as possible. I believe OC is as simple as it gets-EZ
