Product Features :
Metal detector utilizing electromagnetic induction principle, the use of alternating current through a coil to produce a rapidly changing magnetic field. The magnetic field inside the metal object can be an eddy current can be induced. Eddy current will produce a magnetic field, the magnetic field affect the original upside down, causing the detector beeps.
