irOn DiSCriMinatiOn MODe
Don’t search in the IRON DISC Mode unless the area is heavily littered
with iron trash. This mode is better used by hunting in the NORMAL or
AUDIO BOOST Modes and switching to the IRON DISC Mode only to
identify a strong target response. Don’t trust the IRON DISC Mode to
correctly ID weak target sounds. Targets already dug can also be checked
for their gold content by using the IRON DISC Mode. Swing the object
past the searchcoil, holding it in your fingers or in a plastic scoop. If it is
a “hot rock” or small ferrous object, there will be no sound. Some iron
objects chirp or click. If it is nonferrous metal such as gold, your Gold
Bug™-2 will give a solid “beep.”
Unlike the AUDIO BOOST and NORMAL Modes, the IRON DISC
Mode is unaffected by the SENSITIVITY control and threshold settings.
Also, unlike the other modes, the IRON DISC Mode operates without
an audible threshold hum.
NOTE: Some faint static and occasional chatter is normal in this
mode. If you are running your sensitivity too high for ground conditions
(heavy mineralization, trash and or hot rocks) you may experience a
constant, loud chatter as you sweep.
auDiO BOOSt MODe
In this mode, weak signals are louder than in the NORMAL Mode, but
maximum loudness of strong signals is the same. The primary purpose
of the AUDIO BOOST Mode is to help you hear weak signals when there
is interfering noise from wind, mining equipment, vehicles, etc. Also, if
you prefer using the speaker (most people use headphones), you may
prefer the AUDIO BOOST Mode even in quiet conditions.
Hunting in the AUDIO BOOST Mode is best when the area has few
trash items, hot rocks and low ground mineralization. In areas with
many false signals, the AUDIO BOOST Mode will amplify them as well
as signals from gold nuggets. The AUDIO BOOST Mode can also be
used to recheck a disappearing signal, or to check a faint signal to see
if it sounds like a hot rock in AUDIO BOOST.

The moment of truth!
But not so fast . . . take your time. You may have pinpointed a target,
but that doesn’t mean you can reach down and pick up a nugget. Even if
it’s lying on top of the ground, you’re going to have to determine which of
those pebbles really is a gold nugget. And if you have to dig for it, you’ll
have to determine which handful of dirt is pay dirt. But the worst part is
that most of your targets won’t be gold. They’ll be nails, bullets, junk, hot
rocks, etc. The only way to be absolutely sure is to dig them up.
1.
Your objective is to recover your target neatly and quickly, leaving
virtually no trace of your excavation. Repeat: No trace of your
excavation. If you leave the area looking like a battlefield, blame
only yourself if it’s been declared off limits to metal detectors
when you return.
the HOT SPOT was, and quickly mark the target location with
your finger or digging tool.
7.
For very strong signals, you may improve your pinpointing
accuracy by adding one or more of the following steps:
1)
Lift the coil until the signal is just barely heard.
2)
Lower the sensitivity level.
3)
Rest the coil on the ground and move it back and forth very
slowly.
8.
For very weak signals, try the following:
1)
Switch to the AUDIO BOOST Mode.
2)
Move the coil closer to the ground.
3)
Increase the sensitivity level. Recheck your ground
adjustment.
4)
Speed up the sweep rate slightly.
