- Page 4 CONTROLS Meter The meter of the M-97 serves two purposes for the opera- tion of the instrument. When used in the battery test mode, the meter gives a visual indi- cation of the battery strength. A reading between 80 – 100 is desirable.
- Page 5 USING HEADPHONES Using headphones (not included) improves battery life, and prevents the sounds from bothering bystanders. It also allows you to hear subtle changes in the sound more clearly, particularly if searching in a noisy location. For safety reasons, do not use headphones near traffic or where other dangers are present.
- Page 6 SEARCHING It is a good idea to establish a methodic search pattern. Avoid swinging the M-97 like a golf club, swing the detector side to side keeping the search coil the same distance above the ground. Your sweep pattern should be a slow, half-circle motion. If you are searching for a small target, it is a good idea to overlap your sweeps.
