Anywhere here on treasure coast that services detectors. Have a Garrett that was left for a few years with batteries in it. Got some green acid build up and won't work anymore.
I know your plight my favorite one took a mili second dip into a rogue wave as I was scooping with back turned, 4 days later and a lot of hair dyer usage and pulled out hair, finally got it stabile. I was super sad panda for a few days. La my better half likes confiscating the wearable treasure, not sure she would have put up with my negative attitude much longer lol
