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 …
