[PSUBS-MAILIST] Reversed echo sounder

[Alan via Personal_Submersibles]

Hi lasse,
they do use echo sounders for measuring distance to the surface.

It will be easy to test if this works well on your echo sounder, once
the sub is operational.
Wow, big submarine. You will have fun overhauling it. All the best.
