IN THE FIELD TECHNIQUES

- No-motion Pinpoint
In the PINPOINT Mode, coil sweep technique is not important. Rather,
user retuning is critical.
The detector does not automatically adjust to changing ground and
environmental conditions; the operator is required to make the
adjustment. If the detector sounds a constant tone over all areas of the
ground, retune the detector by pressing the PINPOINT button.
Pinpoint is used to find the exact location of a target which was previously
located and identified using the discrimination mode. As this mode does
not require motion over the target, the user can move the coil more slowly
and then narrow the detection field when near the target.
How to Pinpoint
Position the searchcoil an inch or two above the ground, and to the side of
the target. Then press PINPOINT. Now move the searchcoil slowly across
the target, and the sound will communicate the target's location. As you
sweep from side to side, and hear no sound at the ends of the sweep, the
target is located in the middle of that zone, where the sound is loudest. If the
sound is loud over a wide area, the buried object is large. Use Pinpoint to
trace an outline of such large objects.
Narrow It Down
To further narrow the field of detection, position the searchcoil near the
center of the response pattern (but not at the exact center), and press
PINPOINT again. Now you will only hear a response when the searchcoil
is right over the top of the target. Repeat this procedure to narrow the
zone even further. Each time you repeat the procedure, the field of
detection will narrow further.
Consider Purchasing a Pinpointer
When you kneel down to unearth an object, you may find it frustrating as
the object can appear exactly like the surrounding soil. You may hold the
object in your hand, and find it necessary to pass a handful of dirt over the
searchcoil to see if it contains metal. An easier way is to use a handheld
pinpointer. It is a probe-like device which is poked into the ground, making
close up pinpointing a snap, reducing digging time, and minimizing the size
of the holes you will dig. Bounty Hunter offers a robust and inexpensive
pinpointer designed for this purpose.
