Abstract
The present invention relates to a portable detector for metal detection, the detector including: a head extending longitudinally and comprising an inductive transducer for generating a magnetic field and measuring a variation in inductance, a body including a controller programmed to control the activation or the deactivation of a standby function of the detector, and a sensor for measuring one or more of the displacement of the detector or the orientation of the detector, wherein the controller controls the activation of the standby function as a function of signals received from the inductive transducer and from the sensor.
