metal detector

Beachcomber's scanning tool

A metal detector is an electronic device that senses the presence of metal objects.

Handheld models sweep over surfaces to locate buried coins, jewelry, or artifacts.

Walk-through metal detectors screen people entering airports, courthouses, and other secure areas.

The metal detector beeped when he forgot to remove his belt.
