The invention relates to a device for locating metallic objects, comprising at least one transmitting coil (116) and at least one receive winding system (112, 114; 212, 214), which are inductively coupled to one another. According to the invention, the switching means (1, , 8; 1'a, 2'a, 3'a, 1'b, 2'b, 3'b) are provided whereby enabling the effective number of turns of the at least one receive winding system (112, 114; 212, 214) to vary. The invention also relates to a method for operating a device of this type, in particular, a method during which the adjustment of a voltage U induced in a receiving coil ensues by connecting an adjusting winding system (113, 115; 213', 215') to the windings (113, 115; 213, 215) of the receive winding system (112, 114; 212, 214). |
