Hi Chuck.
That sounds like a good idea too. But the easiest
thing of all would be to use a non water activating dive computer that would
just read
the air pressure as if it was water
pressure.

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!
