I was out for a short hunt today and had a strange problem. My explorer was working fine, found a target and dug. Switched to my sunray probe, found the item and when I switched back to my search coil I started getting crazy signals even holding it still in the air. Nothing seemed to make it go away excexcept turning my machine off and then on again. This happened twice today and was wondering if anyone has had a similar experience or help to offer, thanks in advance!
