  • Metal detector coil
    Patent number: 4866424
    Abstract: A coil for a metal detector is constructed from a ribbon cable having a plurality of spaced parallel conductors. The ribbon is formed into a loop where its opposing ends confront each other. The conductors are joined in an off-set manner at the end of the cable to form a single conductor into a loop. Various configurations of coil placement are shown to compensate for various external disturbances such as nearby metal objects, for example.
