3D Metal Detector || Advantage and Benefits
3D Metal Detector There are many differences between a general detector and a 3D detector. One of the main differences is that the typical detector is designed to operate at a frequency lower than that of 3D detectors, to allow the detection of relics, coins and other metals of large conductivity and size. On the other hand, 3D detectors can operate at much higher frequencies even in difficult ground conditions … They can pick up metals, such as gold in particular,...
