Metal detectors are designed to pick up metallic objects in the ground, but when the sensitivity is cranked up too high, it can also detect minerals, electromagnetic interference, or even small metallic debris in the soil, leading to false signals. Another potential culprit could be improper ground balancing. Ground balancing is the process of adjusting your metal detector to account for the mineral content in the soil.

If this setting is not properly calibrated, it can cause the detector to react to mineralization rather than detecting actual metal targets. Additionally, nearby electrical interference could be causing your metal detector to constantly make noise. This interference can come from power lines, electronic devices, or even other metal detectors in close proximity.

Sometimes, simply adjusting your detector’s frequency or changing your search location can help eliminate this type of noise. Now that we’ve identified some potential causes, let’s discuss some possible solutions. Firstly, double-check your sensitivity settings.

Lowering the sensitivity level can reduce the false signals caused by minerals or electromagnetic interference. Experiment with different settings until you find the optimal balance between sensitivity and noise reduction. Next, ensure that your ground balancing is correctly adjusted for the soil conditions.
