Fisher's M-66 Valve and Box Locator is designed specially for finding buried or paved over valves, boxes or vaults. In addition, the M-66 locates survey markers, water or gas meters, conduit, manholes and any other concealed metallic objects. 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.
Fisher warrants the M-66 to be free of defects in material and workmanship when it is shipped from the factory. The terms of this warranty are fully explained in a warranty registration card that accompanies the instrument. Complete factory and field service facilities support the warranty. Warranty may vary outside the U.S. Please see Corrosion Control Products Company for details.
