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.
Fisher’s M-66 has the same mechanical design as the M-97, with a double locking shaft adjustable to 50". Operates on two 9V batteries (included). 2-year manufacturer’s warranty.
Note: The M-66 is only available with a non-interchangeable 8" coil. Detection depth capabilities depend on size of the object and soil conditions.
