Try reducing the sensitivity if you hear too much ground
chatter and false signals. If you find you must decrease the
SENSITIVITY below 5, is probably a good idea to change
the MINERALIZATION setting to NORMAL and set the
SENSITIVITY back to 10. You also might have to retune the
GROUND REJECT control slightly. Remember, when you
switch from LOW to NORMAL MINERALIZATION, you also
slightly decrease the sensitivity of your GoldBug2, and the
retune speed increases slightly. This increase in the retune
speed helps your GoldBug2 ignore abrupt changes in ground
mineralization and hot rocks, but it also results in a slight
decrease in sensitivity.

.
If, after switching to NORMAL MINERALIZATION, you
continue to hear ground chatter and false signals, reduce
SENSITIVITY even
fruther. Still having
problems? You must be
in an area of extremely
high mineralization.
The only way to hunt
this area is in the HIGH
M I N E R A L I Z A T I O N
setting with the MODE
knob in NORMAL.

Keep the bottom of your searchcoil parallel

Sweep the searchcoil continuously at a comfortable rate.
Remember that the GoldBug2 is a motion detector and
responds only when the searchcoil is moving over the ground.

Keep the searchcoil
parallel to and as close to
the ground as possible.
This is important for
maximum coverage and
depth.

Overlap your sweeps at

Search in a methodical
manner and sweep your
searchcoil in a tight

attention to where you are
going and where you have
been.

.
Take your time. If you
walk too fast, you will not
overlap your sweeps, and
you will miss a lot of ground.
If you sweep too fast, you
will lose sensitivity and
miss small, deep nuggets
that normally would be
within the range of your
GoldBug2.

.
Recheck the ground adjustment frequently by raising and
lowering the searchcoil and listening for changes in the
threshold volume. In some nugget-bearing areas, ground
mineralization can change dramatically within a matter of feet,
so check it often.

searching in a tight semicircle around
