While I was out clad hunting with my XT-70 for the first time today I noticed that the pinpoint was getting stuck. It would do the full circle to indicate the center and then stay there as I moved the machine all around the area. It would take a little shake and then it would start working right again. Could this be some kind of loose connection in the box? Also, the rubber liner on the armrest started coming unglued, but I can fix that myself. Is rubber cement enough for this, or should I use epoxy?
