The objective of the effort was to develop a highly sensitive magnetic gradiometer ferrous metal detector packaged in a night stick. The equipment was designed to be camouflaged and otherwise concealed upon the user to permit limited covert operation in the search of concealed weapons. The sensitivity would permit personnel search without touching the person being searched. This report describes the gradiometer function, equipment design and problems and specifies on a flux gate gradiometer which permits a signal of 7.6 gamma measurement in the presence of the earths magnetic field that can be as large as six tenths of an oersted or 60,000 gamma.
