Again, the procedure is to sweep over the target from side to side noting the side to
side center (see step 1 in diagram). Then turn 90 degrees and sweep the coil side to side
noting the center from this new direction (see step 2 in diagram). "X" marks the spot that
you need to dig (see step 3 in the diagram). You can practice with a small pieces of lead
or gold on top of the ground to become acquainted with the technique. It's a good idea to
have a magnet 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
hot rocks too.

Non-Motion Pinpoint Mode

In addition to this traditional method of pinpointing, the GMX also features an all-new,
non-motion pinpoint mode. This is engaged by holding the cross hairs button (large but-
ton in the middle of the keypad). With this button held down the detector will sound off
on targets whether the search coil is in motion or not. Non-motion pinpoint mode disen-
gages the XGB ground tracking, Iron Cancel, and SAT, so in very challenging conditions
you may find that this pinpoint mode struggles to counteract mineralization. But it can be
very useful in sizing targets under the coil and giving you an idea of their shape. For ex-
ample, nails can often pinpoint as an oblong shape with a stronger sound on the flat head.
While in non-motion pinpoint mode the screen will display the signal strength using the
two bottom "swoop" segments as well as the two-digit numeric display. The numeric
display reads from 0-30, with 0 representing a target close to the surface and 30 a target
at the edge of detection. Due to the various size, purity, and mineral content of gold nug-
gets, this scale is not capable of giving absolute depth readings and should only be used
as a reference point for signal strength. It also may give strong readings for extremely
large iron items that can surprise you with how deep they really are. The opposite is also
true- very small nuggets may read as weak targets. So it is best to look at the readings
and sound of the non-motion pinpoint mode as a signal strength, and not a depth reading.

Pinpoint Technique

Due to the wide scan nature of elliptical
search-coils it can be difficult 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 nugget
is in. Because most nuggets are too small
to isolate to an exact location as in coin
or relic hunting, remove 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. (page
