The Fisher M-66 is a no-frills metal detector designed for simplicity. It locates all types of underground metal, including steel, aluminum, brass and lead, plus it penetrates through soil, cement and asphalt.
The M-66’s simplified design with only two knobs helps you attain maximum performance. The sensitivity knob eliminates signals from small items that may be in the ground. Adjust the manual 10-turn ground compensation knob for varied soil conditions.
