its added power for punching through
mineralized ground, it provides the
absolute control available only with
precise dual controls for manual ground
balancing and highly responsive 10-turn
audio control. Circuitry that responds
to signals from revolutionary Crossfire
searchcoils results in greater penetration
to find even the smallest nuggets and
more precise accuracy to locate them.
To prospect for precious metals or hunt
for deeply buried caches switch to the
All Metal mode and ground balance the
detector precisely to your satisfaction
with dual multi-turn controls. A Motion
Discriminate mode is available for
coin, beach and relic hunting. Your
discrimination control will eliminate
unwanted targets. The Scorpion Gold
Stinger is equipped with a 5"x10" elliptical
searchcoil. Other accessories are listed
in this Owner's Manual.

4. Use snap locks to connect the detector
housing to the upper stem/handle.
5. Wrap the searchcoil securely around
the stem; connect to detector. The cable
should be snug but not so tight that
the searchcoil angle cannot be changed
when desired.
ASSEMBLY
Your Gold Stinger is shipped complete in
one carton. No tools are required.
1. Open the envelope which contains a
spring clip, one knob, two washers and a
threaded bold. Compress the button ends
of the spring clip and insert it, button-ends
first, into the lower stem of your detector
so that the buttons pop out of the holes.
This will enable you to adjust the length of
the overall stem.
2. Attach this lower stem to the searchcoil
by inserting the two rubber washers onto
the stem (remove paper backing and
adhere to stem). Insert the threaded bolt
through the holes of the Lower Stem and
searchcoil. Hand tighten the searchcoil
assembly with the remaining knob.
3. Using the pop-out buttons, adjust the
stem to the most comfortable length for
you.

Rotate this knob clockwise to turn the
detector on and test batteries. Additional
rotation increases detection depth and
sensitivity. This control enables you to
detect to the greatest depth possible
in relation to conditions that affect the
sensitivity of your detector's signals.
Rotate the knob back to the left to
decrease or eliminate sounds created by
ground and/or atmospheric conditions.
Audio
This 10-turn control on the lower left
enables the operator to precisely adjust
the level of sound generated by the
detector. This audio level will determine
the amount of sound produced by the
detector when it is searching for and
signaling the presence of metal, either
over its built-in speaker or through
headphones. It is recommended that
the sound be adjusted at a threshold
level where it is barely discernible when
the detector is searching. Any increase
of sound caused by the detection of
CONTROL FUNCTIONS
The Control Panel of your Gold Stinger has
four control knobs, two toggle switches
and one push button to regulate operation
of the detector. The Master (Mode) toggle
switch is on this Control Panel.
Depth (Power)
This control on the upper right has three
functions:
1. Turning the instrument on and off
2. Testing batteries
3. Regulating detection depth

mineral. Any increase in sound caused
by a sample tested at this level indicates
the presence of conductive metal. Ore
sampling is generally conducted in the
TR Discriminate mode with the control
first set at Zero and gradually advanced.
When hunting for coins, jewelry or other
objects in the Motion Discriminate mode,
this control permits the detector to reject
pulltabs and other unwanted trash.
Auto/Manual Tune
This toggle at the left between the
Discrimination and Audio controls selects
Automatic or Manual tuning. Automatic
operation is recommended, especially for
the beginner.
Retune
This small push button control near the
lower center of the Control Panel permits
the operator to retune the instrument as
desired when manual tuning is being
used.
metal can then be interpreted easily by
the operator. Do not adjust the control
when the loud signal of metal detection
is heard.
Ground Balance
This control at the lower right permits
precise ground balancing of the detector's
circuitry in theAll Metal Mode. This cancels
the effects of iron ground mineralization
when operating with the Master Control
switch set to the left at ALL METAL
and these controls are essential when
engaged in electronic prospecting.
Calibrated Discrimination
This control on the upper left offers full
control over the target discrimination
capabilities of the Scorpion Gold Stinger.
This control can be used when the
detector is operating either in the Motion
Discriminate or TR Discriminate mode.
When this control is turned to Zero,
detector circuitry is set at the absolute
calibrated point between metal and

Headphone Jack
Located on the back side of your detector's
control housing.
Headphones are a valuable accessory for
any metal detector to mask interference
from outside noise. They permit
detection of small and deep targets
that might be missed when using audio
from the detector speaker. Headphones
are particularly essential when you are
hunting where sounds of people, running
water in a gold panning stream or other
ambient noise is excessive.
Master (Mode) Control Switch
The toggle switch to the left of the Retune
button on the Control Panel permits
the Gold Stinger to be operated in the
All Metal Mode (with manual ground
balancing) or either of two Discriminate
modes of operation. The Motion
Discriminate mode (switch pressed to the
right) offers automatic ground balancing
and is designed for coin hunting and
other general searching, while the TR
Discriminate mode (switch at center) is
primarily intended for ore sampling and
high grading.
Unless you are engage in electronic
prospecting which requires the All Metal
mode (switch pressed to the left) it is
recommended that you operate in the
Motion Discriminate mode until you
become familiar with the capabilities of
your Scorpion Gold Stinger.

This establishes the optimum audio level
of the Gold Stinger.
If highly mineralized ground or irregular
topographic conditions cause the
instrument to require retuning, simply
press the Tune button on the detector's
control panel for one second. This
retuning enables you to re-establish the
preset audio level as necessary.
A Recommendation
Beginners are advised to use automatic
tuninguntiltheyhavebecomeexperienced
in the use of this detector. Circuitry of
modern detectors has eliminated many
of the problems formerly associated with
tuning.
A Final Word on Audio
Some electronic prospectors achieve
satisfactory performance by operating
silently, just below the level of audible
sound. The theory here seems to be
that the sound made by the discovery of
OPTIMUM AUDIO LEVEL
Automatic Tuning
Turn the detector on with Depth control.
Flip Tuning switch to AUTO position.
Rotate Audio control until only a faint
sound is heard. This is the optimum
audio level of the Scorpion Gold Stinger.
Your detector will now keep itself tuned
automatically to the audio level you
have just selected. This tuning level will
remain the same throughout all operating
conditions as long as the switch remains
in the AUTO position.
Manual Tuning
Turn the detector on with Depth control.
Flip Tuning switch to Manual position.
Flip the Master Control switch to either the
ALL METAL or TR DISC mode. Push and
hold the Tune button. Rotate the Audio
control to achieve a faint threshold of
sound before releasing the Tune button.

OPERATING INSTRUCTIONS
Initial Settings
Your Gold Stinger has initial setting
points (>) located on its control panel.
By first rotating the controls to these
points you turn on the detector (with the
Depth knob) and adjust your audio level
as described in the description of its
controls. As you become more proficient
with your detector, you may wish to make
additional slight adjustments in the Depth
controls in relation to your detector and
the ground over which you are hunting.
Discriminate Mode
Press the Master Control switch to the
right to activate the Motion Discriminate
(automatic ground balanced/trash
elimination) mode. When operating
in this mode, the Gold Stinger detects
only selected metallic objects and is not
affected by ground mineralization.
a target, no matter how small, will cause
an audible tone that will alert the operator.
Charles Garrett, however, recommends
that you listen to a faint sound at all times
whenever the detector is operating.
While hunting in this mode, the operator
will always be aware of whether the
detector is working properly and will know
immediately if some condition of ground
mineralization or atmospheric condition
has caused the audio level to decrease
and require retuning of the Gold Stinger.
If this has happened, and the operator is
unaware of it, valuable targets could be
overlooked.
See the Recommended Reading
section for books that provide additional
suggestions about the regulation of audio
levels and all other aspects of detector
operation and hunting for gold with your
Garrett Scorpion Gold Stinger.
