GMX SPORT Searching
Overload:
The GMX will overload when the coil is over a large object or extremely heavy iron min-
eralization. Lowering the SENSITIVITY will usually cure a mineralized area, but will
not do much to eliminate a real target. If the overload seems everywhere it is probably
mineralization and lowering SENSITIVITY is essential.
Target I.D.:
The GMX has three different target identification systems. First and foremost is the audio
response. In the All-Metal (or ZIP) audio mode, the detector sounds off with a scaled
pitch and volume raise over targets. In Beep mode, the detector will give a high tone for
mostly good targets like gold, silver, brass, and aluminum, and a lower tone for targets
more likely to be iron junk. It also displays a Target I.D. number, using a scale from 0-99.
You might think of this as a "dig percentage" meter, with higher numbers being more
likely to be a good target to dig. There is also a Target I.D. Bar, which gives you a block
in the Iron, Gold, or Alloy ranges. Segments farther on the right of the screen are more
likely to represent good targets.
Misclassifying Iron:
The Target I.D. will consistently identify some types of Iron and Steel objects as non-fer-
rous, particularly flat thin steel such as a can lid, very large pieces of iron, and small
solid pieces of iron like heavy washers. Because this is a gold detector, it was essential to
design it so that it would tend to call doubtful targets "non-ferrous" or "possible gold". In
this way, eliminating the possibility of mistaking gold for iron.
Ground Scan mode tips:
Prospecting takes patience.There are certain areas where the gold is so fine that metal de-
tecting is not an efficient recovery technique You can use the GMX's Ground Scan mode
to track mineral deposits.This is excellent for dry washes, creek beds, and old channels
where you might want to process the dirt using a sluice, dry washer, or gold pan.
Hold the Padlock button on your GMX and the screen will show you the ground phase
(two digit number) and strength (top Target I.D. bar). Find an area likely to contain black
sand (and therefore more likely to have gold) and sweep the coil over the stream bed nor-
mally. Wherever the concentration of minerals are the strongest (Target I.D. bar fullest),
drop a marker. As you continue down your path you will end up mapping the pay streak
with your markers, giving you a lane to work with your recovery equipment. The sensi-
tivity control works in this mode as well. If there is no ground present, the first Target I.D.
segment will flash.

Frequency Shift:

If you find yourself detecting with others, or underneath power lines, you may encounter
EMI (electro-magnetic interference). Turn your GMX off and hold the Iron Cancel button
while powering it back on. Select a different frequency, listen to see if the interference is
gone, and then power the unit off to save the setting.
