Well not that virus, but is not feeling well. My last three hunts (3 locations) it goes nuts with erratic sounds. So much that I can't detect. GRRRR!!!!! I checked the coil cover, shut it off, hit noise cancel many times, moved the alkaline batteries around, checked the coil connection, and my X-1 connection. Sometimes when it's not moving it settles down, but starts back up again when in motion. Any thoughts that it could be the batteries? It has not given me a low battery signals yet.
