RE: [PSUBS-MAILIST] Ambient subs

Hi Greg

I'm in Africa and am also building an ambient sub. (I'm am about 60% done
with the mould - should be done by end March 2002).

I am not sure about the discomfort you are talking about, but you will
basically experience the same pressure/discomfort in an ambient sub as you
would during a scuba dive.  The only major difference is the lack of
breathing apparatus in your mouth and a dive mask - otherwise it is a scuba
dive!   However, it is generally easier (more comfortable) to scuba dive
than to snorkel as in a scuba dive you are weighted and constantly breathing
- when snorkelling you have to fight your buoyancy and hold your breath,
which can be uncomfortable!

I would suggest though, that you try a scuba dive (and the necessary
training) to establish if the discomfort is still present, before going
ahead with an ambient sub .

Good luck
Raoul

Hi Folks -
I have tried submitting this post before, but I never saw it go through.
I am looking at an ambient sub, but my question is this:
Is it uncomfortable to dive to 60 or 125 feet in the sub, i.e. does the
increased pressure make the trip unpleasant.  I have been diving (Snorkel)
to about 15 feet, and it always seems uncomfortable - What is the deal with
going deeper?
Thanks-
Greg

Remember I am not a christ - so for me the Ark never exist ..

The Titanic was designed by professionals with places in rescueboats
for each soul on board - the busisness mans descided that that are to
much
waste space - passengers paid for cabin space - not for rescue places..
and keep the half of the rescueboat places out of the plans..

Today passenger ships have about half rescue space in boats and half in
life rafts - and all the profesionals know's that the life rafts
give you no chance - under the most seaconditions..
