Best Metal Detector VLF System

Very Low Frequency (VLF)

This type of metal detector uses two coils, one sends and the other receives, to pick up on targets in the ground. The sender coil creates a magnetic field that reacts to metal objects. When a target is found, a current is formed, the receiver coil takes the signal and amplifies it to be heard through a speaker or headphones. Many detectors can even translate the signal into a number based on how strong the magnetic current is.

Because of its ability to give information back on targets, there are lots of metal detectors that use VLF technology. The control box is where the magic happens with this type of detector. It interprets the signal and turns it into easy to understand visual and audio cues. Depending on how much work goes into the interface and controls, you can ignore targets you don’t want to dig, see about how deep a target is, change the sensitivity, and much more.

Most detectors are set up for specific types of hunting. For example, the settings on gold detectors like the Nokta Makro AU Gold Finder take into account the hot rocks and ground that are encountered in a goldfield. Some of the newer detectors, like the Garrett AT Max or Minelab Equinox Series, are set up to be used in multiple soil types with preset programs that change settings fairly easily.
