5 Things Not to Do with Your Metal Detector

5 Things Not to Do with Your Metal Detector

Just as crucial as the tips Minelab shares for mastering various terrains with your metal detector, are the pointers on what not to do. Understanding these can ensure your equipment performs optimally, enjoys a longer lifespan, and remains your reliable partner in discovery.

Without further ado, let's dive into the advice. Here we go!


Tip 1: Avoid Iron and Interference

Metal detectors operate across a wide range of frequencies, from 1.5 to 50 kHz depending on your model from Minelab, making them sensitive to noise and interference from sources like:

  • Power lines and transformers
  • Electronic devices generating electromagnetic fields;
  • Highly mineralized soils that can mask or falsely signal items.
  • Iron-rich environments, such as near train tracks, gates, fences, or automotive parts, are also not ideal for your treasure hunting endeavors.


Tip 2: Low Battery Power

Minelab Metal Detectors are designed to operate at a specific voltage, which is dependent on the quality of batteries used. Low-quality batteries can lead to:

  • Incorrect target identification
  • Frequent device shutdowns
  • Difficulty turning on the device
  • Display information failures

To avoid these issues, regularly check and maintain your battery's charge. If your device uses batteries, opt for high-quality ones and keep spares handy for replacement as needed.


Tip 3: Unauthorized Opening, Modification, or Part Replacement

Like any electronic device, Minelab metal detectors should only be opened or serviced by qualified and authorized professionals. Unauthorized tinkering can void the warranty, compromise the device’s specifications, and reduce its detection capabilities. The takeaways are:

  • Don’t open the device for any reason
  • Avoid using non-original replacement parts
  • Always seek service from authorized professionals for maintenance.

This ensures your device remains in top condition and continues to deliver its best performance. Need to contact Minelab's technical support? Our service channel is ready to assist.


Tip 4: Scraping or Digging the Ground with the Coil

We’ve heard from many who’ve attempted to dig deeper by using their coils aggressively. This unnecessary effort can damage the coils, rods, and even the detector's CPU.

During your treasure hunt, ensure the coil hovers about 2 to 4 inches (5 to 10 centimeters) off the ground, without touching it, and remains parallel to the surface. In water, this distance can be reduced due to water resistance.


Tip 5: Cleaning Your Detector

When cleaning your metal detector for the next adventure, exercise caution with your choice of cleaning agent. Chemicals, solvents, or everyday cleaning products can harm the plastic or metal parts of your device. So, what should you use? Simply, water. Use room-temperature running water without excessive pressure, and avoid:

  • Cleaning chemicals (as mentioned above)
  • Rags or wiping cloths
  • Scouring pads (never use these).

Easier than you thought, right? Now you know how to keep your metal detector clean, you're ready to plan your next destination!

Maintaining Your Detector is Key

As you can see, proper care and maintenance are essential for your metal detector to function correctly, unlocking all its potential and ensuring successful treasure hunts.
