Abstract

The present invention relates to a portable detector (1) for metal detection, the detector including:

• • a head (11) extending longitudinally and comprising an inductive transducer for measuring a variation in its inductance and/or for measuring parasite currents caused in the metals to be detected, and
  • a body (13) including a controller programmed to control the activation or deactivation of a standby function of the detector, and a sensor for measuring displacement of the detector (1), and/or for measuring the orientation of the detector (1), the controller (20) controlling activation of the standby function as a function of signals received:
    • of the inductive transducer on the one hand, and
    • of the sensor on the other hand.

Claims

5. The detector according to claim 3, in which the controller controls the activation of the standby function if the orientation value is such that the head of the detector extends in a horizontal plane.

6. The detector according to claim 4, in which the controller controls the activation of the standby function if the orientation value is such that the head of the detector extends in a horizontal plane.

7. The detector according to claim 1, in which the sensor is a three-axle accelerometer.

8. The detector according to claim 1, in which the controller controls the deactivation of the standby function as a function of the signals received from the sensor.

9. The detector according to claim 8, in which the controller controls the deactivation of the standby function if at least one of the following conditions is verified:
