In ambient sub senses the same pressure inside or out so there
is no difference having the gage inside or out.

Hmmmm... Not
the weight of the sub. It should indicate the depth of the vent where
the air is released into the
surrounding water and likely a little deeper since the constant flow of air may
add a few psi to the ambient cabin. Air at the top of the cabin is at the
same pressure as the air at the bottom of the cabin where it is vented to the
surrounding water. So it does not matter where the gauge is inside the
cabin.
That also makes the air at the top of the cabin at a pressure higher than the
water surrounding the top of the cabin. So a hatch in the top of an ambient sub
seals naturally if it opens inward. Completely opposite to a 1ATM sub.
In my case the dive computer is going to ride along outside the forward view
port. There is no room for it inside and with it outside it will automatically
start logging the dive when it submerges.
So what are you thinking of building?

In an ambient
submarine, if one uses a dive watch type depth indicators to give an indication
of how deep He is, does this display the actual depth or will it be off a
little having the additional weight of the sub working on it? One of those
HMMMM thoughts...
