When the metal detector is classified, they are divided into two extensive categories. The first type essentially provides a single regional metal detection system, and the second type of type provides multi -regional metal detection.
For some multi -regions walking, passing the metal detector (such as Garrett MT 5500), the metal target is detected on the left or right.
A good example or example shows the differences between a single area and a multi -region through the metal detector. If a person passes through a metal detector with a metal object on his left hand, a single and multi -regional detectors detect metals.
However, for multiple metal detectors, it will be able to accurately distinguish the location of the metal target object.
In fact, for other advanced multi zone walk through metal detectors such as Gerrett PD6500, the exact locations where the metals may be on the individual will be shown from head to toe as well as from the right side to the left side.
For this reason, a multi zone metal detector is usually recommended, especially in areas where a large crowd needs to be processed.
Examples of Multi Zone Wall Through Metal Detectors include;
1. Fisher M-Shape Portable Walk through Security Metal Detector
2. Garrett Magnascanner MT 5500
3. Garett PD6500i
Examples of Single Zone Wall Through Metal Detectors include;
1. Garret Magnascanner MS 3500
2. Garret Magnascanner CS 5000
Basic Locations and Applications of Walk Through Metal Detectors
Before now, metal detectors were usually found only in correctional facilities and airports. However, that has changed today because walk through metal detectors are now seen in many other places such as schools.
Other places where metal detectors are used today include; night clubs, police stations, private and public facilities for the security of the workplace. Also, metal detectors are found in places such as historical landmarks, warehouses, transportation terminals, manufacturing facilities, nuclear facilities, courthouses, sporting arenas and others.
Setup/Installation and Operation of Walk Through Metal Detectors
Most modern walk through metal detectors are very easy to install and operate. This is because each security walk through unit usually comes with an instructional setup video together with a detailed manual of installation.
For digital electronic components, these ones can easily be adjusted using a LCD unit or a touch pad. Also, most metal walk through detectors comes with an inbuilt factory program. With this, it then becomes very easy to adjust your metal detector to suit your location as well as the type of target objects you want it to detect.
More so, you can also adjust the sensitivity of your metal detector for quick detection of the slightest metal object within its range of operation. Nevertheless, when setting up your metal detector walk through, it is important to consider other permissible metal objects in which people may want to pass through the machine with. With this, it then become important to have a basket or a tray where they can drop their metal object before passing through the detector system.
Finally, when setting up metal detectors, it is important to exclude metal objects such as keys, belt, watches so that the security checks will be well organized and fast.
