How Hand Held Metal Detectors Work

You don't need to understand all the science of how a hand held metal detector finds various metals. You can find coins, rings, jewelry, gold, relics, artifacts, small buried caches and even deep treasures without knowing scientifically how a hand held metal detector works. It is even easier to operate a hand held metal detector when using for detection of weapons.

Follow the instructions supplied by the manufacturer and turn on your hand held metal detector.

Next test your hand held metal detector on some surface targets (coins) to make sure it is working.

Notice the "red" signal pattern being transmitted from the searchcoil into the ground. As long as the signal entering the ground does NOT come in contact with metal, there will be no audio signal, no flashing light, no vibration, nothing will happen.

When the search pattern touches metal it interrupts the transmitted signal and this interruption or disturbance of the search pattern will cause the hand held metal detector to alert the detector user with an audio signal, usually a distinct loud sound. In some cases flashing or blinking lights will accompany the audio signal.
