OK I think I figured it out after reading a bunch of old posts. But now I have another question about the HDS 7 Touch, an old post mentioned that the touch screen glitches unless the transducer is touching water to ground it? Is there a solution for this if the transducer is mounted in hull?
Baja Traveler I am looking at it for my Solo Skiff, just picked it up last sat.
