Joan Allen Metal Detectors

Using ideas that you, our valued customers, have passed on to us, the M-97 Valve and Box Locator stands as the new and improved addition to our line of highly successful M-95 and M-96 Locators.
The M-97 is an all-metal metal detector that can search through concrete and asphalt and was 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.
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 one year limited warranty comes standard with the unit.
