Detected Metals. Metal detectors detect iron, nickel, copper, brass, aluminum, tin, lead, gold, silver and bronze. General-purpose metal detectors can find buriedmetal objects such as jewelry, coins and other metal objects. “Discrimination” is a process that distinguishes between different metal targets or alloys
Hand held metal detector is a portable electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground.
When electricity flows through the transmitter coil, it creates a magnetic field all around it. If you sweep the detector above a metal object (such as this old gray spanner), the magnetic field penetrates right through it. The magnetic field makes an electric current flow inside the metal object.
As a generalisation, a stock standard middle of the range metal detector is capable of finding targets up to and often more than a foot deep. That’s 300mm to those who no longer use feet and inches.

Can Metal Detectors detect Bullets?

You can absolutely detect bullets using a decent quality metal detector or even a pinpointer if you can already locateaccurately the ammunition. Indeed, bullet’s composition is mainly based on electrical conductor metals.
