“PUSHBUTTON” GROUND BALANCE METHOD
This will probably be your method of choice in all but the most difficult of ground conditions. It’s fast, easy and accurate. You can use this method in either the Autotune or Target ID mode.
1.With your controls set as in the
2.Still pressing the PINPOINT button, lower the coil to the ground. Starting at 10, rotate the GROUND control clockwise until you hear an audio tone. Then back it off to the exact point where the tone disappears. Release the PINPOINT button and you’re ready to search.
NOTES:
1. If you get an audio response as you first lower the coil with the GROUND control at 10, you’re probably over a piece of metal. Move and try again.
2. If you get a sudden belltone not proceeded by an increasing audio response as you lower the coil, you’re probably in some very highly mineralized soil or sand. In this case, it’s best to use the “Bobbing” method.
3. If you don’t get any audio response, or just a very faint one as you rotate the GROUND control from 10 all the way to 0, you’re probably in an area where there’s very little ground mineralization. Just leave the GROUND control at 10 and begin searching.
4. Recheck your ground balance occasionally and make sure you haven’t accidentally moved the MODE switch.
“BOBBING” THE SEARCH COIL METHOD
This method takes a little more practice, but you may find it slightly more accurate with fewer false signals from ground minerals.
