A
little cleaner setup might be to use an acrylic box that is sealed but vented to
the outside by a couple of tubes. One to bring in the outside water pressure and
one to vent the air out of the box. That way no water is sloshed aroud in the
bucket.

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!
