Metal Detector Model M-96

Metal Detector Model M-96

Description

md.jpg (9280 octets) The M-96 Valve, Pedestal and Box Locator is specifically designed for finding buried or paved-over valves, boxes or vaults. It also locates buried survey markers, water or gas meters, conduit, manholes and other metal objects. These objects can be made of aluminum, brass, copper, iron, lead, nickel, steel, tin or any metal.

Accessories

The M-96 also accepts a larger optional 11-inch diameter search coil for deeper ground penetration and wider scan.
Part. No. 2036227
An optional soft, padded, vinyl carrying bag keeps the M-96 free of dust and dirt.
Part. No. 103693
For the ultimate in protection and convenience, an optional hard-shell carrying case with foam padding keeps the M-96 safe and sound.
Part. No. 202767

Auto-Tune

Special Auto-Tune circuitry provides a continual, but very gradual, retuning of the M-96 operating frequency to counteract any drift caused by temperature and humidity changes.

Pushbutton Tuning

The M-96 incorporates features not found in any other valve, pedestal and box locator. Pushbutton tuning makes for quick and easy maintenance of the meter level and the "threshold" level of the sound. The "threshold" level is a low tone heard during normal operation when the M-96 is correctly tuned to existing ground and temperature conditions. Pushbutton tuning also allows the operator to "detune" the M-96 for pinpointing the location of buried or covered metallic objects.

Two Sensitivity Modes

The NORMAL MODE provides adequate sensitivity when searching for larger objects, such as manhole covers, valve boxes and pedestals. While in the NORMAL MODE the M-96 is not distracted by smaller metallic items, such as tin foil, pull tabs or other metallic trash.

In the HIGH MODE, sensitivity is increased for locating deeper and smaller objects. Tuning must be more precisely adjusted for prevailling ground conditions.
