Fisher M-97 Valve & Box Locator

The Fisher M-97 is specially designed for finding buried or paved over valves, boxes, or manhole covers, or any other concealed metallic object. It also locates targets made of aluminum, brass and lead. The M-97 features push button tuning allowing the user to quickly and easily maintain optimum sensitivity for easy pinpointing of buried metallic objects. Plus, the M-97 offers auto-tune circuitry and a waterproof search coil.

New to the M series is the ease with which the M-97 can be stored. Just compact the lower stem, twist the search coil 90 degrees, and fold the search coil flat. The M-97 fits easily into the optional carrying case. In the Fisher tradition, the M-97 is affordable, tough, and simple to use while providing maximum performance. A two year limited warranty comes standard with the unit.
