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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
