Troubleshooting

Problem Possible Cause Suggestion
The metal detector is emitting false signals in the field. Sensitivity may be set too high. Adjust sensitivity back slightly until the false signaling disappears.
You may be moving the search coil too quickly. Swing your search coil slowly.
You may be over highly rusted metal, which can cause false signals. If the signal does not repeat over the same area while passing the search coil over it, then the target is usually not worthwhile.
The display is not locking in or identifying while passing over a target, and the metal detector emits more than one tone over the same target. There may be more than one object in the area you are sweeping. Search another location.
It may be an odd piece of metal that the detector cannot recognize. Search another location.
Soil oxidation may be causing the display ID arrows and tones to jump around. Search another location.
Sensitivity may be set too high. Adjust sensitivity back slightly until the false signaling disappears.
The metal detector is not stable and has a pulsing, distorted tone (rather than a clear tone). The area you are searching may be trashy. Search another location.
Adjust the ground balance.
The metal detector does not function or operates erratically. Another metal detector may be within 15 feet of your metal detector. Move to another area.
Do not operate two or more metal detectors within 15 feet of each other.
The detector emits a constant loud tone or repeating tones. The batteries may be weak. Replace the batteries with new ones.
