Abstract
A hobby-style metal detector includes a two-piece stem interconnected by a hand grip and provided with an arm rest. A search coil is positioned at the lower end of the first section of the stem and an electronic housing is mounted on the first stem section near the hand grip. A metal detector circuit, a display and operator controls are provided with the electronic housing. A second housing is detachably connected to the second section of the stem in conjunction with the arm rest. The second housing contains batteries and can be detached and clipped to the operator's belt to reduce the weight carried by the operator's arm. A speaker can further be included within the second housing thereby removing additional weight from the arm carried unit. A cable is provided to extend from the second housing to the electronic package for providing the battery power to the metal detector circuit. When a speaker is provided in the second housing, a further line is provided in the cable for the detection signal. The cable is preferably a coiled cable which is inserted within a second section of the stem when the second housing is mounted on the metal detector.
