Joan Allen Metal Detectors

The Fisher F70 Metal Detector operates on 13kHz frequency - good for coin shooting, relic hunting, and gold prospecting. Frequency shift for eliminating electrical interference and crosstalk. Advanced software-based motion discrimination with notch for searching trashy areas. All metals auto-tune mode for deep-seaching in non-trashy areas. Visual target ID by category & 0-99 indication, both discrimination and auto-tune modes.
