A visual representation of conductivity values measured by the Minelab Equinox 900 metal detector, this resource helps users interpret detected signals and differentiate between various buried metals. Typically presented as a numbered scale or a color-coded chart, it correlates conductivity readings with likely material composition, aiding in target identification. For example, a high conductivity reading might suggest silver or copper, while a low reading might indicate iron or foil.
This interpretive tool provides a crucial advantage for detectorists. By offering a framework for understanding signal responses, it allows for more efficient searching by enabling users to discriminate between desirable targets and unwanted items. This reduces time spent digging up trash and increases the chances of recovering valuable finds. The development and refinement of such charts reflect advancements in metal detecting technology and contribute to the growing sophistication of the hobby.
