ABSTRACT:
A metal detection apparatus that detects metal objects includes a nonmetallic basket in which the metal objects are retrieved. The nonmetallic basket has a top portion, a side wall portion, an open bottom and a blade portion for scooping material into the basket through the open bottom. The basket is attached to one end of a handle. A metal detection coil for detecting the metal objects is pivotally mounted with respect to the basket so that the metal detection coil is normally in a first search position proximate and at least partially covering the open bottom for detecting metal objects, and pivots to a second position within the basket as the basket fills with dirt and other material. The basket preferably has apertures in the top portion so that the basket, when inverted, can sift the material for metal objects.
