[PSUBS-MAILIST] Sonar thru hull wiring

[Alec Smyth via Personal_Submersibles]

Hi Brian,

There are surely more sophisticated ways to do it, but my approach was to
use a two conductor through-hull with the signal through one conductor and
the shield through the other. It works fine, although my sounder is pretty
basic.

Best,
Alec
