Some embodiments of the invention relate to a mobile detection device embodied as a bucket of an earth moving machine for an evaluation of a distance value and/or proximity from the bucket to an occluded AC-current carrying structure according to the magnetic field emanated from the structures AC-current. There is at least one detection coil, comprising at least one winding of an electrically conductive material, which is connected to a first amplification stage, with an amplifier circuit embodied as a current sensing amplifier, which are both are sealed within a common enclosure that is located at the bucket. An output of the amplifier circuit is configured to be linked to an electronic signal evaluation unit for detecting the occluded structure according to an electrical signal induced in the detection coil by the magnetic field.
