Fisher M-66 Valve & Box Locator

with 8" Search coil
Fishers M-66 Valve and Box Locator is designed specially for finding buried or paved over valves, box’s or vaults. In addition, the M-66 locates survey markers, water or gas meters, conduit, manholes and any other concealed metallic object. The M-66 detects all metals including aluminum, brass, copper, iron, nickel, steel or tin. Combining sensitivity and accuracy with maximum ground penetration, the M-66 eliminates any guesswork when pinpointing hidden metallic objects.

The electronic balance of the M-66 is easily and quickly tuned for detection within seconds while also allowing for maximum audio and visual indications. In the Fisher tradition, the M-66 is affordable, tough, and simple to use while providing maximum performance. A two year limited warranty comes standard with the unit.
