Noisy Detectors in Highly Mineralized Terrains

Noisy Detectors in Highly Mineralized Terrains

A peaceful day of metal detecting can quickly turn frustrating when your detector incessantly chatters and buzzes. Often, this noise is a consequence of high mineralization in the soil. 

But in order to fix noisy detectors in mineralized terrains, first we need to understand why metal detectors behave in this manner, and then we can diagnose the real problem and work on solutions.

At GoldXtra, we are here to guide you so that you can tackle the challenges and issues you face while metal detecting and, most importantly, how to avoid them.

Why Detectors Get Noisy

  • High Mineral Content: Soils rich in minerals, especially iron, can produce constant signals, causing the detector to sound off more frequently.
  • Overly Sensitive Settings: Sometimes, a detector set to a very high sensitivity will pick up even the minutest mineral signals, leading to noise.
  • Interference from Other Electronics: While not exclusively due to mineralized soils, nearby electronic devices can exacerbate the noise in such environments.
  • Improper Maintenance: It is important to keep your detector clean as if some small metallic particles get stuck on your detector through mud, it might cause interference with the detection of objects underground.

Impact of Noisy Detectors

  • Missed Discoveries: Constant noise can mask valuable finds, leading to missed opportunities.
  • Decreased Efficiency: Continually checking false signals can be time-consuming and tiring.
  • Frustration: A constantly buzzing detector can make the experience less enjoyable for the enthusiast.
  • Prohibit the use of metal detectors: Constantly annoying others while metal detecting could in severe cases lead to metal detecting becoming prohibited in certain areas.

Strategies to Quiet Down Your Detector

  • Ground Balancing: By adjusting your detector to the specific mineralization of the soil, you can reduce the number of false signals.
  • Adjusting Sensitivity: Lowering the sensitivity might decrease the noise. However, it’s essential to find a balance to avoid missing genuine targets.
  • Use Specific Modes: Modern detectors often have modes designed for mineral-rich terrains. Make sure to utilize them when needed.
  • Double-check with Pinpoint Mode: If your detector has a pinpoint mode, use it to verify if the detected object is worth excavating. You can also read this article: What is metal detector pinpointer? for further information about the pinpoint mode.
  • Use Headphones: If you have tried all the other ways but the detector still won’t stop making noises, and you don’t want to disturb others just so you can treasure hunt, then headphones are your best bet.

Additional Tips

  • Frequent Calibration: Regularly calibrating your detector can help maintain its accuracy in challenging terrain.
  • Invest in Quality Headphones: Good headphones can help you distinguish between genuine signals and mere noise. Remember that the quality of headphones matters a lot.
  • Practice: Spend time in mineralized areas to become familiar with your detector’s responses in such conditions.


High mineralization can indeed make a metal detector act like a chatterbox, but understanding and addressing the root causes can make your treasure hunting more efficient and enjoyable.

With the right adjustments and a touch of patience, you can tune out the noise of the noisy detectors in mineralized terrains and tune into the treasures hidden below.

Also, make sure that your metal-detecting journey is not a cause of annoyance for others. If your detector makes a lot of noise, consider using headphones, as disturbing others while metal detecting will lead to the activity getting prohibited in certain regions and becoming a hassle for others as well.

That’s it for this article, Now you know what steps you need to take if your metal detector is getting noisy and ruining your metal-detecting experience. Be sure to stay tuned for more guides regarding metal detectors, common mistakes people make, and of course, how to avoid them.
