When at the airport, mall, or amusement park, you might have been screened. Security precautions are taken to keep everyone safe. One of those safety tools is metal detector, which detect any metal object inside pockets or other areas. Metal detectors have evolved greatly. They can now easily identify guns, knives, or other harmful items. Check out some things you must know about metal detectors.

1. Use of metal detector
A metal detector makes use of electromagnetic induction to identify metals. The technology, although been used for years, has recently involved wherein they have become compact. The applications of metal detectors today are commonly used as walk-in detectors or handheld detectors.

2. Maintenance
As the metal detectors have no moving parts, these do not require any maintenance. However, you can consider ensuring the connection is well and the auxiliary is well established and clean for the walk-through detectors. While for the handle-held detectors, make sure the batteries are charged and up-to-date.

3. Security level
Many people doubt if you can fool the metal detectors, and the answer is no. Unless you have tried carrying a metal object through the metal detector, you will not understand it. The metal detector uses the magnetic field to identify metal objects. So even though the security person gets fooled, the device is highly advanced and can identify the metal presence even in the deeper section.

4. Portability
Both handheld and walk-through metal detectors are highly portable. However, it is a hand style that is easy to carry everywhere. The walk-through metal detectors must be secured on the ground or can simply be installed at the entry points with a good power source.

5. Metal detectors vs. baggage scanner
Although metal detectors are highly advanced and used mainly for detecting metals, most dangerous items like knives and guns at the airport are detected using baggage screening. It is simply because people have recognized that the metal detectors cannot accelerate the work. At the same time, those using them cannot rely on them to fully check the person. Thus, it is vital to pass the items through the baggage scanner.
In a closed environment, metal detectors can easily identify a metal object. However, there is a need for an x-ray machine for the investigation as it offers a proper interpretation.

Purchase the best metal detectors
The metal detectors offer security to a great extent. However, they are no longer a means for treasure hunting. Instead, it has become a popular choice in the cinema halls, amusement parks, and other areas to help keep the people and the property safe. If you want to purchase a metal detector, Treasures in America can offer you the best. They have a wide range of security detectors suitable for every requirement. With them, you can purchase fair-priced metal detectors and other security systems.
