Operation in the Field
Sweep the search coil from side to side, in slow, overlapping motions.
Keep the search coil parallel to the ground.
Keep search coil 1/2” off the ground and try not to make contact with the ground.
Try not to lift the search coil at the end of your sweeps. This may be difficult for
younger children, but the closer the search coil is to the ground throughout the
sweep, the more likely you are to find buried metal objects.
Keep the left knob in the maximum sensitivity setting possible.
Click the right knob on and start searching with it in the fully counterclockwise
position.
You may want to move the right knob during your search, depending on what
you find. For instance, if you start searching with the right knob to the left(but
not in battery test mode), you will detect all types of metal objects. If you find
that you are in a trashy area, and wish to eliminate unwanted objects from
detection, sweep the search coil over an undesirable object while turning the
knob. Find the knob setting at which certain types of metals are eliminated, and
adjust your settings accordingly.
CAUTION:
Gold rings can be eliminated from detection along with pull-tabs.
Be aware that some desirable objects, like nickels and gold, are
eliminated from detection in the middle of the range. Gold rings have a
metallic signature similar to pull-tabs; nickels have a metallic signature
similar to some newer pull tabs. It requires practice and patience to
understand what types of objects are eliminated at each setting.
Pinpointing
Accurate pinpointing takes practice and is best accomplished by “X-ing” the sus-
pected target area.
1
.
Once a buried target is identified by a good tone response, continue
sweeping the coil over the target in a narrowing side to side pattern.
2
.
Take visual note of the place on the ground where the “beep” occurs
as you move the coil slowly from side to side.
3.
Stop the coil directly over this spot on the ground.
4
.
Now move the coil straight forward and straight back towards you a
couple of times.
5
.
Again make visual note of the spot on the ground at which the “beep”
occurs.
6
.
If needed, “X” the target at different angles to “zero in” on the exact
spot on the ground at which the “beep” occurs.
REMEMBER:
The detector will beep just as the search coil passes over the
buried object.
If you have difficulty pinpointing very strong signals, try lifting the coil higher
off the ground until a weaker, but more concise, signal is heard. For very
weak signals, try moving the coil in short quick sweeps, closer to the ground.
