Hi Jay,
What is the resoluion like? I have a digital compass in my Jeep and its good down to eight 45 degree segments: N, NE, E, SE, S, SW, W NW. For a sub I would like to see something better then 10 degrees. Else by the time you know you are drifting off course you are way off course.
Regards,
Ray

Another option that is very economical and adopts easily to different magnetic fileds if you dive in different areas is a magnaflux compass. Mount outside the hull with a digital readout inside. No moving parts and very reliable.

The magnetic compass wouldn't work inside the steel sub. I originally had it closer to the viewport but it still didn't work there. It works somewhat out on the fiberglass MBT but even out there it's not really reliable. That's why I installed a gyro compass.
