ABSTRACT:
A sifting scoop attaches to a metal detector. The scoop is movable relative to the detecting head to multiple operating positions. In a storage position the scoop is held on the shaft of the detector above the head where it will not interfere with the metal detecting operation. In a scooping position, the scoop is extended below the head for digging at a spot located by the detector. In an optional third or sifting position the scoop is held up close to the head to retain articles during sifting. The scoop walls are perforated to retain articles while discarding sand.
