![]() This is where higher-end models shine as well. When an object is found, an alarm sounds and indicator light strips activate, indicating where the object is. High-end metal detectors have the ability to sense smaller objects, while some cheaper models have less sensitivity and can only detect larger ones. For instance, while some metal detectors can only sense ferrous (iron-based) objects, others have the ability to detect non-ferrous metal objects. This is where the capability range of metal detectors can be seen. This magnetic field then reacts with the receiver coil, which, in turn, triggers the alarm. As metal passes through this field, sensors detect the reflected magnetic field from these metal objects. In short, a surge of electricity is passed through a copper wire coil, which creates an electromagnetic field. Most metal detectors use either pulse or continuous wave technology. In order to get a better idea of which metal detector to choose, it helps to know the answer to one question… How do walkthrough metal detectors work anyway? The Metor even has optional radiation detection. These models boast super-accurate 33-point displays and robust security. Some of the big daddies at the top of the food chain are the Garrett PD6500i and RapiScan Metor 6E. Another is the Metor 6M, which can be set up in minutes with no prior experience. ![]() For those who are concerned about the budget, there are low-feature options such as the Zorpro 18-zone metal detector. The fact is, there are many options available when it comes to metal detectors, all at varying price points and with different features. Perhaps you are considering walkthrough metal detectors for your place of business or education. And depending on where you work or go to school, metal detectors may also be a daily occurrence for many. ![]() ![]() We don’t really think about it: we know it keeps us and everyone else safe. Walkthrough metal detectors are something we’re accustomed to when flying. ![]()
