Garrett Ace 300i; bought new in September, approximately 10-12 hours of use. Took it out today, and as soon as I turned it on, it was pinging non-stop, all over the scale, and didn't matter what I did; even up in the air away from anything that could trigger it.
Changed batteries, and when I turned it back on, for a minute or so, it wouldn't detect anything, even resting on my shovel. Then, it went crazy again...
Took it home, opened up the head unit, totally dry and no sign of water ingress and no sign of any damage to any component on the board. The only other sign is that the LCD indicators (all of them) look just slightly less "black" than normal, even with fresh batteries.
Does anyone have any insight? Coil or head unit? I'd like to get my hands on a schematic and a pin-out for the coil.
Thanks!
Edit: Turns out it was moisture after all; the "slightly less black" appearance of the display was due to a super-find layer of moisture, which I couldn't see until I actually started looking at it with a loupe. It looks like a very small amount of water (literally a couple of drops) entered via the speaker grill (Possibly from putting it down in wet grass or something). A couple of hours over the furnace vent and all seems good again. As a low-level protective measure, I've put some clear packing tape over the grill openings.
