Hey all just was wondering if anybody has had the same problem I am having with my Etrac...I got it in Jan. of this year and have probably 2 or 3 hundred hours on it and it's always been fine but yesterday and today all of a sudden it's been going beserk....I checked my coil cover (stock coil) and cleaned that checked the coil connections and everything seems tight. It worked yesterday after messing with it for quite a while and then today worked ok for a bit and now it's nuts again. Numbers going crazy even when the coil is high in the air. This is an old area I have detected before with no problems as far as underground or overhead lines or anything. Don't know if it's a bad coil maybe or control unit. Would it be a good idea to do a master reset? Don't know if that would do anything for this problem or not but didn't want to erase my patterns that I got off the net with the exchange software but guess I could reload them if need be. Sorry for the long message but hopefully somebody has an idea so I don't have to send it in. Thanks for any helpful ideas and HH.
