This type of metal detector utilizes a visual display to represent the probable conductivity of detected objects. This graphic representation, often coupled with an audible signal, aids in discerning valuable finds from undesirable items like iron or foil. For example, a high conductivity reading on the display, accompanied by a distinct tone, could suggest a silver coin, while a low conductivity reading and a different tone might indicate a rusty nail.
The technology offers significant advantages to detectorists. The visual identification system streamlines the search process, reducing the need for extensive digging to identify every detected object. This minimizes ground disturbance and preserves historical sites. Furthermore, the increased accuracy in target identification improves the recovery rate of desirable objects, making the search more efficient and rewarding. The development and refinement of this technology represent a significant advancement in the field of metal detection, moving beyond simple detection to sophisticated analysis of buried objects.
