Pinpointing
Pinpoint Technique
Due to the wide scan nature of modern search coils
it can be diffi cult to locate small targets under the
physical center of the loop. Use an "X" marks the
spot technique as shown in the diagram to identify
the portion of ground the metal target is in. Pros-
pecting for small nuggets, because small metal
targets are more diffi cult to isolate to an exact loca-
tion compared to coin or relic hunting, may require
removing the soil under the center of the "X" until
the target is no longer in the hole, but in your pile
of dirt. Techniques for examining the pile of dirt are
discussed later in the manual.
Again, the procedure is to sweep over the target
from side to side noting the side to side center. Then
turn 90 degrees and sweep the coil side to side not-
ing the center from this new direction. "X" marks
the spot that you need to dig. You can practice with
a coin or small pieces of lead or gold on top of the
ground to become acquainted with the technique.
During Prospecting it is a good idea to have a mag-
net handy, preferably in the handle of your digging
pick, to pull iron out of the dirt pile. It will speed
up your recovery time. It will work on small almost
invisible iron rocks as well.
