What to do if your metal detector experiences high levels of electromagnetic interference (EMI)?

  1. Move to a different location: EMI can be caused by a variety of sources, such as power lines, electrical equipment, and even cell phones. Moving to a different location can sometimes help to reduce interference.
  2. Check for sources of interference: Look around for any sources of EMI that may be causing interference with your metal detector. This might include electrical equipment, power lines, or even cell phones.
  3. Shield the metal detector: You can try wrapping the metal detector in a shield made of aluminum foil or other conductive material. This may help to reduce EMI by blocking the interference from reaching the metal detector.
  4. Use a ground balance setting: Many metal detectors have a ground balance setting that can be used to help reduce interference caused by mineralized soil.
  5. Use a lower frequency: Some metal detectors operate at higher frequencies, which can be more sensitive to EMI. Using a metal detector with a lower frequency may help to reduce interference.
  6. Use a different metal detector: If you are unable to reduce the EMI interference with the steps above, you may need to try using a different metal detector that is less sensitive to EMI.
