A hand-held metal detector is a device used during a search, with the help of which it is possible to determine the presence of hidden metal objects on the person being searched. A metal detector is used to search for metal objects hidden under clothing or in luggage.
Application area
Hand-held metal detectors are usually used in two cases: to localize an object detected using a stationary metal detector, and in situations when an inspection is necessary, but the use of a stationary metal detector is impossible for a number of reasons.
Operating principle
The operating principle of a hand-held metal detector is based on the intersection of two electromagnetic fields: the one created by the device and the one emitted by the metal object under the influence of another electromagnetic field. Changes in the electromagnetic field are recorded by the electronic circuits of the device and converted into alarm signals. B2scan hand-held metal detectors are made of impact-resistant plastic and have a low weight, the tone of the alarm signals changes depending on the weight and distance of metal objects.
Main advantages
- The advantages of hand-held metal detectors, first of all, include compactness. Not everywhere it is possible to install arched metal detectors, but hand-held metal detectors can be used almost anywhere.
- Hand-held metal detectors are powered by built-in rechargeable batteries, the charge of which lasts for a long time.
- Ease of use, according to the principle: “plug and play”.
- Ease of use of a hand-held metal detector does not require special knowledge from a person.
