I took my B&G appart and found a couple of cold solder joints. Re-soldered and this fixed the intermittent problem I was having. It seemed that everytime it was time to set up to drop the hook the depth
gauge would stop working. I think the engine
vibration at that speed would knock out the circuit. I also had a Garmin
that packed it in, No signal in. Tried different antenae. Just before ordering a new one I thought I would take it appart. I used a film loupe and checked things out and found a single
strand from braided wire had fallen across the input connectors signal pin to ground. Enough to kill the input signal. Removed it and all is well. I figure if anything electronic is working for you it's a good day.
