Understanding how metal detectors operate?

<p>Metal detectors work by transferring an electromagnetic field from a search coil to the ground. If a metal object falls under the electromagnetic field relayed by the metal detectors, the metal object in the ground becomes energized and transmits its own electromagnetic field.</p> <p><br></p> <p>Metal detectors can identify buried items on the basis of their transmission and ferrous properties. This is called the discrimination ability of a metal detector. There are four main types of discrimination in Minelab metal detectors. The simplest type is variable discrimination that utilizes a control knob to adjust discrimination levels.</p> <p><br></p> <p>As a valuable item is found, an audible response by the metal detector alerts the user. There are several<strong> </strong><a href="https://www.metaldetectingshop.com">Minelab metal detectors</a><strong> </strong>that can visually display information about the target like ID numbers and 2D display.</p> <p><br></p> <p>Listen to this episode to learn how metal detectors operate.</p>
