With that in mind, it is important to take note of the two different types of walk through metal detectors. The first style of security walk through metal detectors provide a single zone detection meaning that it can detect targets in one place on the human body. Check out the Fisher M-Scope Walk Through Metal Detector for a great single zone detector.

2. Multi-Zone Metal Detector

The second style of walk through metal detectors provides multiple zones of detection meaning that it can detect targets in more than one place on the human body. Both types of detectors will be able to locate the target but the multi-zone detector will be able to accurately identify the target’s location. Some of the most popular multi-zone detectors are the Garrett PD 6500i Walk-Through Metal Detector and the Garrett MZ 6100 Walk Through Metal Detector.

More advanced multi-zone metal detectors can pinpoint from head to toe and left to right on a person. Being able to accurately pinpoint the location of the target is important so that a security team can respond quickly and effectively. Larger crowds will require more through put and a multi-zone metal detector will let security teams be able to process individuals faster.

How Much Does A Walk Through Metal Detector Cost

According to Total Security Solutions, a manufacturer of bulletproof barriers, stand-alone metal detectors can cost anywhere from $1,000 to $30,000. However, on average they cost around $5,000. Kellyco’s selection of security walk through metal detectors ranges from $3,000 to $5,000.

Since walk through metal detectors can move more people through security checkpoints faster, they are no longer just located in correctional facilities and airports. Today, these detectors are found in police stations, schools, nightclubs, government buildings, corporations, manufacturing facilities, nuclear facilities, transportation terminals, warehouses, courthouses, historic landmarks, arenas, and concerts. Some detectors are even lightweight and portable so they can easily be moved from one place to another.

How To Set Up a Walk Through Metal Detector

Most modern walk-through metal detectors are easy to set up and operate. They come with a detailed instruction manual and a video to help security teams get setup more efficiently. Settings on these devices can be adjusted with just the push of a button through a touchpad and LCD display. Walk-through metal detectors come with a factory preset program and can be adjusted to meet the needs of a specific location or type of object needing to be found. The detector can also be adjusted to locate a variety of target signals based on a chosen sensitivity level.

Controlling traffic to the walk-through metal detector, by ensuring people make their way to the device, is important to a building’s security. Security teams want to make sure that signs and line ropes guide people to the device. By having a basket or tray set up next to the walk-through metal detector, people can move through quicker thus allowing for a smoother line. It’s also a good idea to make sure individuals remove and place items such as watches, keys, coins, belts, and any other large metal objects into the baskets so the device doesn’t trigger a false positive.

Walk-through metal detectors, in general, are a great screening device. After an individual has been identified as having a concealed item, it is then necessary to utilize a metal detecting security wand to accurately pinpoint its location. The wand will allow security personnel to find the item quickly and sometimes discreetly with either audio, light, and/or vibration alert.

Having a system in place like the walk-through metal detector is essential to a facility’s security. They are easy to use and make security screenings more efficient as well as more affordable. Coupled with a metal detecting wand, the walk-through metal detector is a powerful tool in building and facility security.
