Abstract
A portable electromagnetic metal detector includes a detection head placed at the end of a support stick. The detection head includes a transmitting coil and a receiving coil. The metal detector has, an electronic command and control box making it possible to operate the detection head. An operator headset is provided for allowing the detector to transmit an audio detection signal to the operator. According to the invention, the generation of the transmission signal and the analysis of the received signal are made in the detection head. The detection head, the electronic box and the operator headset furthermore linked two by two by a multipoint wireless communication network. This wireless communication network advantageously makes it possible to provide a detector that does not include any wired links and to implement the detector according to the invention in various configurations including the three elements or not.
