How to Properly Maintain Your Metal Detectors

tools for maintenance

If you've invested in a metal detector, you’ll likely already know that they don’t come cheap. And whether you've got a basic model or a high-end machine, keeping it in good shape is key .

Don’t forget - good maintenance isn't just about protecting your investment, but about making sure your detector performs its best every time you head out. So, let's talk about what you can do to keep your metal detector in tip-top condition, even when you’re using it frequently..

The Importance of Maintenance

So, why is maintenance important? It’s simple - regular maintenance on your metal detector is key to its longevity and performance, helps you avoid costly repairs and keeps your detector working consistently. There's nothing worse than missing out on a great find because your equipment isn't up to scratch.

Basic Maintenance Tips

Let's start with the basics - these are things you should be doing after every detecting session.


After a day out, your detector is probably covered in dirt, dust, or sand. Take a few minutes to clean it properly. For the control box and shaft, a damp cloth usually does the trick. Just be careful not to get water into any openings. The coil can handle a bit more water, but don't submerge it unless it's designed for underwater use.

For this, it's worth knowing about different metal detector coil types, as each type might need slightly different care. It’s a good idea to familiarize yourself with what you've got to make sure you’re employing the right methods.


Where you store your detector matters. Ideally, you’ll want to always keep it in a cool, dry place away from direct sunlight and heat, as extreme temperatures and humidity can mess with the electronics. If possible, store it disassembled - this reduces stress on the joints and connections, so it’s likely to last longer. You can also use a carrying case if you have one, which helps protect it from the elements and general wear-and-tear in transit.

Battery Care

Taking care of your detector's batteries is another key aspect here, and you should always remove them if you're not planning to use the detector for a while. This prevents battery leakage that can seriously damage your machine.

If you're using rechargeable batteries, don't let them drain completely before recharging. Partial discharges and recharges are actually better for battery life.

Inspecting for Damage

Every so often, give your detector a thorough check; look for any signs of wear and tear, especially on cables and connections. Catching small issues early can prevent them from becoming big problems later on, so it helps to be proactive.

Advanced Maintenance Techniques

Once you've got the basics down, here are some more advanced tips to consider.


If you often detect near water, think about waterproofing your detector. If you’re paying for a premium device or a high quality underground water detector, these generally come waterproof out of the box. For others, you might need to apply additional measures when detecting on the beach or near water.

Software Updates

For digital detectors, software updates can be an important part of maintenance. Like with a PC or phone update, these updates can improve performance, add new features, or fix bugs. Check the manufacturer's website regularly for any available updates and install these regularly for optimal performance.

Long-Term Maintenance Considerations

Thinking long-term? Here are some things to keep in mind for the extended life of your detector.

Professional Servicing

Even with regular maintenance, it's a good idea to have your detector professionally serviced every few years. A pro can spot and fix issues you might miss and can perform more in-depth maintenance.


Keep a log of your maintenance activities: note when you perform routine maintenance, any issues you encounter, and any repairs or part replacements. This can help you track the health of your detector over time and can be useful if you ever need to make a warranty claim.

Lifelong Learning

Metal detector technology is always evolving, so it’s worthwhile staying informed about new maintenance techniques and best practices. Join online forums, read detector magazines, or attend metal detecting events to learn from other enthusiasts.

Final Thoughts

All in all, maintaining your metal detector might not be the most exciting part of the hobby, but it's an important element in the process. A well-maintained detector is a reliable detector, and reliability is key when you're out in the field.

Remember, these maintenance tips are general guidelines. Always refer to your detector's manual for specific care instructions, as different models and brands may have unique maintenance requirements.
