How to Take Care of Your Metal Detector

Metal detecting is a great hobby where, with just one good jewelry find, you can recover the purchase of your metal detector and its accessories. Take care of your investment and enjoy its many rewards.


  1. 1
    Follow the instruction manual. Keep the manual, do not discard it. Download the manual from the internet for ease of viewing. Also, heed the advice of others who own metal detectors on the care of metal detectors, as they will have some good advice for you.
  2. 2
    Consider having an extended warranty or to purchase a metal detector with a lifetime warranty. Know what the warranty covers, for example, most warranties won't usually cover accidents and neglect.
  3. 3
    Shield your metal detector by keeping it in a case, box or thick bag when not in use. Buy a case or make a duffel type bag. Make a custom cardboard box, for your detector: you will need cardboard, paper glue, a box cutter, tape measure and tape
    • If you disassemble your metal detector when not using it, always remove the coil from the non-metal rod.
    • If you always have your metal detector fully assembled, keep it safe from damage - the metal detector is a somewhat fragile device because it is made from lightweight materials. At home, store your detector(s) so they will be safe, such as on a rack.
  4. 4
    Protect the monitor, toggle switches, battery access cover and knobs by making a little hood using cardboard and duct tape. Make your protective hood easy to remove and apply, by using a cord to attach the hood (like a chin strap for a helmet). A hood is space efficient, but if space is not a problem, use plastic foam sheets or cushioned fabric and wrap it like a bandage around the metal detector's main housing.
  5. 5
    Do regular checks of the coil and headset wires at their connection points and protect the copper prongs at the wire ends.
    • When using your detector, periodically check that the wires, if removable, are securely connected. Do not let dust, dirt, sand, water and especially salt water get into areas hard to clean. Check the wires so there are not excessive stressed at their connections. The headset wire and connection is not too robust, do not stress it.
    • If your wires, when not assembled, have delicate prongs, protect these prongs from breaking by using the prong shields that came with your detector.
  6. 6
    Be careful with the wire connections to: a) the coil, b) the headset to the main body of your detector and c) the coil wire to the main body of your detector.. Do not put pressure on the connectors when assembling and disassembling your detector. When metal detecting, be aware of any stress at the wire connections, and if there is stress, immediately adjust the wire wrapping on the pole.
  7. 7
    Transport the headphones in a cloth bag. Use one that is light and well cushioned. At the very least, store your headphones in a doubled-up plastic bag.
  8. 8
    Protect your detector from the elements. Unless you have a waterproof metal detector, buy a clear plastic hood or use a clear plastic bag for protection from water, sand and dust when necessary. When laying down your metal detector, keep it away from sand and dirt.


  • Purchase a coil cover. A coil cover is a good investment. When swinging your coil, look at the ground and keep away from it. Coils can be pricey, make your coils last.
  • Batteries leak. It is recommended that you remove them when not metal detecting. Consider using NiMh batteries for their economy, because they are rechargeable, and because they do not leak. A leaking battery will be costly, so avoid it.


  • An purpose metal detectors that can be immersed in water and salt water, will not have wire connections like the wire connections of a metal detector specifically made for underwater use. Check your all purpose metal detector wire connections periodically when using your metal detector in water, so water, especially salt water, does not get into the wires and the main housing.
