Abstract: Disclosed is a frequency-modulation type metal tracker, relating to the technical field of detecting instruments. The frequency-modulation type metal tracker includes a metal tracking transmitter which can modulate a wireless frequency-modulation tracking signal and broadcast the wireless frequency-modulation tracking signal to the outside through a metal object, and a metal tracking receiver which can receive the wireless frequency-modulation tracking signal from the metal tracking transmitter, demodulate the wireless frequency-modulation tracking signal, and reproduce information of the wireless frequency-modulation tracking signal. The present disclosure mainly solves the problem of how to provide equipment that can remotely detect and track metal objects.
