Why does my Oshion MD-A1 sound false signals?

  Billy MilesAug 7, 2025
  If your Oshion Metal Detector is giving false signals, it might be due to a few reasons. First, the sensitivity could be set too high, or there might be electromagnetic interference in the environment. Try reducing the sensitivity. Also, ensure you're not sweeping the search coil too fast or at the wrong angle; sweep it more slowly and maintain the correct position. Lastly, if you're using multiple detectors, keep them at least 6 meters (20 inches) apart.

  If your Oshion Metal Detector isn't detecting anything, there could be a few reasons. First, check if the sensitivity is set too low and increase it. Another possibility is that the target range has been eliminated; recover all target range. Finally, make sure the search coil is parallel with the ground and adjust the angle if necessary.

What to do if Oshion Metal Detector LCD displays multiple target categories?
- N
  Nicholas RodriguezAug 29, 2025
  If the LCD of your Oshion Metal Detector displays multiple target categories or emits several sounds, it could be because there is more than one kind of metal in the target items. Try reducing the sensitivity to eliminate the detection of the deeper target. Also, the detector might be unable to identify the target, so sweep the search coil with different angles. Sometimes, oxidized metal can also cause this issue.
