TARGET RECOVERY
you hear may be your hand. Instead, use the sprinkle
method. Test the sensitivity of your Gold Bug-2 to your
hand by waving your empty hand in front of the
search coil. If it's a large target, you may use your
hand. The loud signal from a large target will mask
any signal produced by your hand.
5. If the target sounds small (faint and soft), sprinkle
some of the target dirt on top of the Gold Bug-2
search coil. If you get a response, you can set aside
the rest of the dirt in your hand and concentrate
on the dirt on your coil. If you get no response from
your coil, sprinkle more dirt on the coil until you hear
a signal. By repeating this process several times you
should be able to identify even a very small target.
CAUTION: Use the sprinkle method sparingly and
carefully. If you wear a hole in the top of your search
coil, it won't be covered by our Lifetime Warranty.
6. Recheck your target area to make sure you're not
leaving a second target behind.
7. Scrape all loose dirt back in the hole and move on
only after the area appears as it was before you
got there.

MODE AND MINERALIZATION SWITCHES
The MINERALIZATION switch adjusts your Gold Bug-2 for ground
conditions. It does this by decreasing or increasing the sensitivity
(or gain) of your Gold Bug-2. Unlike the SENSITIVITY control, the
MINERALIZATION switch also affects the retune speed, which is
the amount of time it takes for your Gold Bug-2 to automatically
retune itself after the search coil has passed over a target. A fast
retune speed means a quick response to targets.
The following is a brief description of the MODE and
MINERALIZATION settings.
1. NORMAL MODE: This is an all-metals, autotune search
mode used for most nugget-hunting conditions. The
sensitivity is normal and the retune speed is fast.
2. AUDIO BOOST MODE: In this mode, your Gold Bug-
2 automatically amplifies faint target sounds. At
volume levels above 7, faint target sounds continue
to get louder while loud, shallow target sounds
remain constant.
3. IRON DISC MODE: This mode ignores hot rocks and
small ferrous objects. It also features a very sharp target
response. An independent mode, the IRON DISC mode
is unaffected by the settings of the MINERALIZATION,
GROUND REJECT and THRESHOLD controls.
4. NORMAL MINERALIZATION: With the MINERALIZATION
toggle switch in the NORMAL position, the sensitivity
of your Gold Bug-2 is optimum for most gold-bearing
soils. The retune speed is fast.
5. LOW MINERALIZATION: This setting is used for ideal
conditions – areas with few hot rocks, little black sand,
low ground mineralization and little trash. The LOW
MINERALIZATION setting provides better sensitivity
and slower retune speed for better response to
smaller, deeper nuggets.
6. HIGH MINERALIZATION: In this position, the sensitivity of
your Gold Bug-2 is reduced to allow operation in areas
of extreme mineralization. The retune speed is fast.
