Metal detectors are one of the most common security devices used to prevent any criminal activity as they can detect weapons including guns and knives and even land mines or bombs.



One of the more commonly used types of metal detectors used in large buildings, schools and airports are walk through metal detectors which can detect metal on a person as they pass through the detector. Modern walk through metal detectors can also detect the exact area where a metal object is on a person but these solutions tend to be more expensive.



However, one of the more convenient types of metal detectors that security officers can use for inspection is the hand held metal detector. This kind of metal detector is commonly used to detect metal on a person's body or the bag they carry. They are ideal for use in establishments that see a high number of people come through their doors such as schools, and airports.



Unlike walk through metal detectors where an alarm is triggered when metal is detected but don't always pinpoint the exact location of the object, had held metal ...
... detectors can immediately identify metal objects while the security officer manually scans the person's entire body.



Handheld metal detectors consist of a speaker, control box, batteries, and microprocessor which is connected to a shaft with search coil that sets off the alarm whenever it moves over a metal object.



Handheld metal detectors are low maintenance device and can be easily operated with only a short training session and are also more accurate and portable meaning that they can be used at any time in any place. Dependant on the application, covert models are also available, as well as models disguised as gloves and ones which vibrate as opposed to setting off an audible alarm.
