Types of Metal Detectors: VLF, PI, and BFO | Gear Up.

VLF metal detectors are more sensitive to ground mineralization than PI Detectors, which can lead to false signals and decreased performance in highly mineralized areas. Ground mineralization can cause the detector to produce signals for non-metallic objects, like minerals or wet saltwater sand, making it challenging to identify actual metal ...

How Do VLF Metal Detectors Work – MetalDetector

This type of VLF detector sends out signals across multiple frequencies simultaneously. VLF metal detectors send out a low-frequency signal that is then reflected back to the detector when it comes into contact with metal. The strength of the signal depends on the type of metal and its conductivity. VLF machines are good at detecting a …
