Gold Metal Detectors | Kellyco | 855-910-6955

Detectors with VLF circuits are very gold-sensitive but are also sensitive to other minerals in the ground. However, these detectors can be set to filter out much of the interference caused by the other minerals. Pulse induction detectors are good at ignoring tough ground mineralization and locating larger gold nuggets at greater depths.
