I got one! If I took an air tank and lobbed off the bottom to it and placed it such that the lower part was down deep in the water within an ambient submarine. A small metal tube was then attached to the upper or output end and ran up to a pressure gage. Would this show pressure in psi as can be converted to the depth of the sub?
