Metal Detector Frequency Explained: What kHz Actually Controls and Why Higher Is Not Always Better
A detector’s operating frequency influences how strongly it responds to different target sizes, shapes, conductivities, and ground conditions, but the kHz number cannot predict performance by itself. Higher-frequency implementations often respond well to very small or low-conductivity targets, while lower-frequency implementations may favor larger or higher-conductivity targets, yet coil design, recovery behavior, filtering, ground handling, … Read more
