Typical uses will include body search for offensive weapons in crowd control, airport and border security, checking parcels and letters for metal objects and anywhere that hidden metal needs to be detected. The application of hand held metal detector are applied to all kind of industries widely.

Generally speaking, The working principle of hand held metal detector is similar. Firstly, an oscillator creates radio waves along a coil of wires. Then the receiver in the metal detector picks up the radio waves and produces a beeping noise. When a metal object passes near the wire coils, a magnetic field is created that alters the radio waves being sent to the transmitter and also alters the beeping noise so as to indicating to the user that metal has been found. Operators should learn hand held metal detector usage to detect metal in many situations, especially for security purposes.

Try to remember that the signal could be a beeping sound, a vibration or a red LED light turning on. In addition, you can set any special features on your hand-held metal detector, such as plug-in ear phones, volume controls or sensitivity controls.

4. The last step is to hold your hand-held metal detector as close as possible to an area where you need to search for metal. The closer the metal is, the clearer the signal is.

Actually the working principle of hand held metal detector is very simple because of  its unique design. The information above will give you a close understanding of hand held metal detector usage. I hope you can use the hand held metal detector better after reading this hand held metal detector tips.
