3. PINPOINT
Enter PINPOINT from either Disc or All
Metals mode. Press and hold
to
activate pinpoint. Pinpoint detection is
only active for as long as you keep
depressed.
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
(2.5-5cm) above the ground, and to the
side of the target. Then press and hold
. 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), release
, and then
quickly press-and-hold it 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.
Teknetics offers a robust and
inexpensive pinpointer designed for
this purpose.
