Claim:
1. A metal detector, comprising: a detection head comprising a transmitting coil and a receiving coil: a supporting rod connected with the detection head, wherein a first control printed circuit board (PCB) is located inside the supporting rod, and is electrically connected to the transmitting coil and the receiving coil; and a headset comprising a second control PCB connected to the first control PCB by wireless communication, at least one a speaker electrically connected to the second control PCB, and a display electrically connected to the second control PCB; wherein when an operator wears the headset, the detection head detects a metal signal, the first control PCB receives the metal signal and transforms the metal signal into a first electrical signal, and the first control PCB transmits the first electrical signal to the second control PCB by wireless communication, the second control PCB transforms the first electrical signal into an audio signal transmitted to the speaker and a video signal transmitted to the display to display for the operator, wherein the headset further comprises a left earphone, a right earphone, and a connecting part, and the headset comprises a pair of speakers, and wherein one of the speakers is located inside the left earphone, and another of the speakers is located inside the right earphone, the connecting part protrudes from an exterior surface of the left earphone, and bends toward a front of the headset, and wherein the display is positioned at a tail end of the connecting part, wherein the headset further comprises a camera and a microphone, the camera is positioned at the connecting part and electrically connected to the second control PCB, and the microphone is positioned at a bottom of the left earphone and electrically connected to the second control PCB.
