Right on Paul.
You could put your dive computers into a small
bucket of water inside the dry sub and then the pressure in the sub
pushing against the water in the bucket should
register the interior pressure and make your dive computers depth gauge
work.

So treat an ambient dry sub like a dive with a big
scooter. I haven't thought much about ambient subs but this has prompted
some rules I might set for myself:
* Be a certified diver. The
education on dive physiology and just general comfort underwater is
crucial.
* Assume you'll be exiting in an emergency. I'd think
entanglement is one of the more likely accidents, particularly for those of us
interested in shipwrecks. :-) In cold water wear some kind of exposure
suit - I can't see myself wearing my drysuit but at least a thicker wetsuit
would help. Weight belt, mask, survival gear, personal bail out bottle,
maybe a 40cf pony? That could be a lot of gear... but still less
than you'd wear on any normal cold water dive. Store an ascent
line/spool in an exterior compartment. Think what you'll do on the
surface, minus your diesel/electric boat. :-(
* Have partial
droppable ballast - as Rick describes. And it sounds dangerous to have
fully droppable ballast. Right?
* Carry your dive computers and
dive a plan. I've done recreational diving with tables and with just one
computer but would probably spring for a backup computer of a different model
than my primary computer. Yes, in a dry ambient you'd have to trick them
into thinking they were submerged.
It seems like this being out of
the water, even in a small sub may keep you warmer, and make it easier to
manage gear, particularly breakdowns. You can easily talk to your dive
partner because he's sitting right there behind you. I like it. I
have some of the slowest ears ever for diving and have the hope that
equalizing in air may be easier for me than in water. Also need to try
the ProEar2000 mask or some kind of helmet, which would be much easier than
building a sub to test this idea. :-)
Great discussions on this
list!
Paul
