What is Metal Detector Frequency?

Metal detector frequency refers to the number of electronic waves a detector sends into the ground per second. Technically, the frequency is measured in Hertz (Hz), and in the context of metal detectors, this figure can range from a low of around 1.5 kHz to a high of 100 kHz or more. Essentially, this feature defines the operational behavior of the device and is a key element in determining the efficiency and type of metal detection.

The choice of detector frequency has significant implications for the performance of a metal detector. Lower frequencies are generally better at penetrating deeper into the ground and are more effective at detecting larger objects. They tend to provide better results for finding highly conductive metals like silver but are less sensitive to smaller objects and less conductive metals like gold.

Conversely, higher detector frequencies excel in sensitivity, particularly suitable for finding small pieces of metal and fine jewelry, especially gold nuggets. However, these higher frequencies may not penetrate as deeply into the ground as lower frequencies and are more susceptible to interference from mineralized soils.

When choosing a frequency finder bug detector, it’s vital to consider the primary use of the metal detector. For instance, if the primary goal is relic hunting, a lower frequency may be preferable, as relics can be both large and located at significant depths.
