TR1
Garmin no longer makes the TR1. They have switched to a new auto pilot that runs on electric motors rather than hydraulics and interfaces with the chartplotter rather than a compass. I've got a TR1 - love it. Worth every penny.
Also, went to braid for the downriggers so the voltage thing is moot. Can't believe how much nicer the braid is over the cable. Quiet, no splicing, no kinks, no wire slivers in my fingers, and much smoother.
