The detection disc 1 is detachably mounted with a fixing ring 4. The upper surface of the fixing ring 4 is provided with a moving mark structure 5 extending to the lower surface thereof. The moving mark structure 5 comprises a moving structure for moving the detection disc 1 and a marking structure for marking the detected area. The moving structure comprises a mounting frame 51 fixedly connected to the bottom of the fixing ring 4, an auxiliary wheel 52 rotatably connected to the inside of the mounting frame 51, and a transmission shaft 59 fixedly connected to the shaft center of the auxiliary wheel 52 and extending to the outside of the mounting frame 51. The detection disc 1 is the induction part of the metal detector, located at the bottom of the device and directly contacting the ground. It is internally provided with a coil for detecting metal objects by emitting and receiving electromagnetic fields. The transmitting coil generates an alternating magnetic field, which penetrates the ground and induces eddy current. The receiving coil detects the change of the eddy current caused by the metal object and converts the change into an electrical signal. The detector display screen 2 is the human-computer interaction interface of the metal detector, used for displaying the detected signal information, helping the operator to judge whether a metal object is found and the size, depth and other information of the metal object. The detection disc 1 and the detector display screen 2 are electrically connected.
