Technology Used in Metal Detectors

Description:

As a type of device that can either be used for security or used as a treasure finding device, a metal detector is a machine that contains a few simple parts for proper use and may take advantage of a few different kinds of technologies to function properly. The first type of technology is called "VLF" and stands for Very Low Frequency. This method is the most popular that's used today and is a type of induction balance. Another method used is called VLF phase shifting which allows a detector to distinguish between different types of metals.
