A vibration can be felt in the wearer hand. 

Working of a Metal Detector

The metal detector works on the principal of electromagnetic induction which creates a magnetic field with the help of the inductor coils. The first coil allows the electricity to flow when the detector comes in touch with the body. The second coil acts as a receiver which will detect when a metal which is there will change the magnetic field. This information will be transmitted to the metal detector which will signify that some metal is there.
