A support assembly for a metal detection device is disclosed. The detection device includes a housing with a central orifice, an induction member surrounding the orifice for generating an output voltage when a metal object is passed nearby, and a mechanism which includes pulse emitting and pulse receiving members for selectively sensing an object passing through the orifice. The support assembly includes a base member having front, rear and opposed side portions sized and shaped for positioning beneath the housing. The base member has a central aperture adapted for substantial alignment with the housing orifice when the base member is positioned beneath the housing. A mechanism secures the base member to the housing, and a plurality of mounting posts are disposed along the base member front, rear and side portions for positioning a metal detection device induction member about the central aperture. A mounting mechanism is provided for the pulse emitting and pulse-receiving members on opposite sides of the central aperture. Finally, a plurality of pulse regulating elements are provided for eliminating ambient light interference and cross-pulse sensing. |
