TARGET RECOVERY (continued)
You can find an elusive target in a handful of dirt by pouring it
on top of your Gold Bug™-2 searchcoil. If the first handful doesn't
produce a target, pinpoint your target again and grab another,
sprinkle it on the searchcoil, and repeat the process until you've
identified your target (hopefully a gold nugget). Remember, many
gold nuggets look just like a brown clump of dirt until you get
them home and wash them off. Only your Gold Bug™-2 knows
the difference in the field.
5. If the target sounds small (faint and soft), sprinkle some of the
target dirt on top of the Gold Bug™-2 searchcoil. 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 searchcoil, 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 (continued)
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 searchcoil 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 Metal, Auto-Tune 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.
