Query: Don't expect to find anything

The detector arrived with no shipping damage and was easy to set up, however the users manual could have been more detailed. In using the detector it seemed very erratic it its identification of metal. It would beep as you swept over an area and then once you dig down a ways and try to continue to hone in on the metal it would stop beeping having found nothing. Adjusting the sensitivity didn't seem to help and so far the detector has been pretty unusable in its intended purpose. Going to try it with headphones to see if that helps.
