The XP ORX with 9-inch HF coil supports 21 selectable frequencies ranging from 13 kHz to 81 kHz. You choose one frequency at a time based on your ground mineralization and target type. The highest frequencies (50 kHz and 81 kHz) deliver extreme sensitivity to small gold nuggets and shallow coins, while the lower frequencies in the range penetrate deeper on larger targets. This single-frequency VLF architecture gives you precise control over detection behavior, though it requires more operator skill than simultaneous multi-frequency platforms.
