RE: [PSUBS-MAILIST] Another nutcase here.



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!
