Metal Detector Double-D Search Coils (DD) Explained

The benefits of a Double-D coil are stability (especially in heavily mineralized ground), good depth, sensitivity and a very thorough search pattern requiring less overlap. When used with GPX detectors, Double-D coils (unlike Mono loop coils) are able to discriminate between ferrous and non-ferrous targets when Iron Reject is activated.

Metal Detector Circuit: An Introduction Guide

Metal detector circuits use an oscillator that produces alternating currents. An eddy current passes through the metal when active. Hence, the current produced passes through a coil. Doing this creates an alternating magnetic field. The magnetic field attracts the metal closets to the coil. As a result, the metal changes the magnetic field ...
