MX5 issue dicovered and fixed.

When I turned on MX5 today after having not used it in a month or so the numbers and tones were jumping around. Checked the battery connections, all looked good. Tried 3 coils, still had the same issue. Took a magnifying glass and inspected the coil connection and found very fine green corrosion where the 3/4 inch nut touches the flat washer, I'm talking very fine, almost to little to even see. I keep a housing cover on the detector at all times so would not noticed it even anyway . Last time I had used the detector was at the beach and it was a very misty day that day. Only thing I can think is when I got home and washed it off, must have not gotten all the salt water rinsed off at the coil connection. Loosen the 3/4 inch nut cleaned the very minor corrosion off and tighten the nut back up. Fired the MX5 back up, ground balanced it and all is good again. Tried 3 coils again running just like it came out of the box from the factory. I hope this helps if anyone else experiences the same problem.

Merry Christmas and HH

How did you ground balance it,I thought it was ground tracking only?

Each time I changed coils, I just put it in all metal mode and bob the coil a few times. Yes auto track will kick in very fast as well, just something I do when switching coils.
