A detector for finding metal objects being disposed in garbage includes a driving coil, a receiving coil, and a voltage detector. The driving coil encircles an opening formed in a ring-like lid for the trashcan. The controller connects to the driving coil and oscillates a driving current in the driving coil . A receiving coil is disposed parallel to the driving coil and has an current induced therein from the driving current in the driving coil. The voltage detector connects to the coil and detects changes in voltage of the inducted current when a metal object passes through the driving coil and the receiving coil. The coils can be constructed from a flat ribbon coil containing a plurality of parallel wires. The flat ribbon coil can be supported under a trashcan lid by a support.
