My Metal Detector is not operating properly, what do I do? Problems Possible Causes Possible Solutions False signals Electromagnetic interference (EMI) Extreme humidity Sensitivity set too high Sweeping too fast or wrong angle Multiple metal detectors used in close proximity Move to a different search area Reduce sensitivity Sweep slowly, keeping the coil level and 1 – 2 inches (2.5– 5 cm) from the ground Keep metal detectors at least 20 ft. (6 m) apart Erratic/multiple signals Multiple targets Highly mineralized soil Reduce sensitivity Move to a different search area Detector fails to detect anything Sensitivity set too low Target-ID is filtered out Search coil at wrong angle Increase sensitivity Re-enable that target-ID in DISC mode Adjust search coil to be parallel with the ground Detector does not function at all Flat battery Disconnected search coil cable Charge the battery Reconnect the search coil cable plug into the DIN connector Related articles What are the detection modes?
