In our experience, many faults that occur with metal detectors are in fact not faults at all but simple mistakes, oversights or misunderstandings by the owner. Some of the following troubleshooting tips may seem obvious or a little silly, but we have all done it from time to time. So it is worth a quick read through our list of ‘first aid’ checks prior to packing you metal detector off for repair.

First read the instruction manual. If your detector is not doing as it is supposed to, it could be you have misunderstood a function or setting.

I switch on and nothing happens?

  • Check the batteries. Make sure the batteries are fresh and are the correct type.
    (It is a good idea to try a couple of sets to eliminate the chances of a dead battery).
  • Check that they are in the right way round.
  • Check for loose leads or connectors.
  • If your model had a detachable search head, ensure this is plugged in as some will not work without.

The screen is on but there is no sound?

  • Check you have the volume turned up (if applicable).
  • Check headphones and adapters. Many headphones have an 1/8th inch plug as standard with a ¼” adapter to fit your detector. Ensure when headphones are unplugged the adapter is not left in the detector.
  • Check headphones. Does your detector work with them or without them?
  • Check the discrimination settings. If accidentally set to maximum chances are, everything you try to detect will be eliminated.
  • Check the search head is plugged in properly. If possible try another search head.

My detector work but it is noisy or chattery and false signals all the time?

Check sensitivity levels, try lowering the sensitivity.

One of the most common causes of noisy detectors is electrical interference and every detectorist will experience this from time to time. All you can do is lower sensitivity and soldier on or try your metal detector in another place preferably at least 200 meters from where you had the problem.

I accidentally got my detector wet and now it does not work.

The most important thing here is to remove the batteries as soon as possible. This is because the water will cause damage through short-circuiting components. If there is no power this cannot happen.

If your detector got wet with fresh water or rainwater, a few days in a warm place such as an airing cupboard should be all that is required.

If it was sea water (salt water) the corrosive effects of this on the circuitry will disastrous if not dealt with immediately. Unless you are competent enough to open the control box and manually dry the circuitry we would recommend you contact your service center and have them do it as soon as possible.
