How It Fits the Lineup
The Fisher F70 sits in Fisher's lineup alongside Fisher F44, Fisher F75, Fisher Gold Bug 2, Fisher F22. It uses VLF (Very Low Frequency) — a single transmitted frequency, typically 3–81 kHz. VLF machines discriminate well — telling iron from silver by phase response — and are light and affordable. Their weakness is mineralized ground and wet salt sand, which read as false targets.
