This is Falcon MD20 Gold Detector, metal detector for gold prospecting in rocks. We are using it in alluvial gold operations to detect gold in rocks and types of rocks that could be additionally crushed and grinded to recover gold out of them. Detection is pretty fast and efficient. It can distinguish between the black and and gold. Pyrite is usually not detected.
