TO THE OWNER
Congratulations on your selection of the Garrett
Tactical Hand-Held Metal Detector (THD™). The
Garrett THD is an active hand-held metal detec-
tor designed to detect metallic (ferrous, non-fer-
rous and stainless steel) weapons, contraband
or other metal objects concealed or carried on
a person. The Garrett THD has both visual and
silent (vibrating) alarms and offers outstanding
performance as well as operating features not
found in other hand-held detectors. With 360°
Plus tip detection coverage, the detector is very
effective in easily detecting even the smallest
of metallic objects. Unique LED lights indicate
target detection, operating status and battery
life information. A bright LED flashlight at the tip
of the Garrett THD assists in dark and low light
conditions.

SAFETY NOTICE
Safety precautions have been designed into the
detector. The THD meets CE and other interna-
tional standards for electromagnetic compatibility
and safety.
Extensive research has found no information that
would indicate Garrett products have adverse
effects on pregnancy or medical devices or mag-
netic recording media. Directives of physicians
and medical device manufacturers must be fol-
lowed.

COMPONENTS AND FUNCTIONS
Power Button
Easy push button power switch turns the power of
the detector ON and OFF.
Light Alerts
• Red LED light illuminates when metallic target
has been detected.
• Green LED light remains illuminated while the
detector is ON and will change to AMBER when
the battery needs to be replaced. (Approximately
1 to 2 hours of use remain once the AMBER
light appears. No performance degradation takes
place until the battery is fully depleted; when this
occurs, operation becomes erratic.)
LED flashlight
When the THD is ON, the LED flashlight button
may be pressed and held to activate the bright
LED flashlight at the tip of the unit. The LED
flashlight turns off when the flashlight button is
released.

Vibrator
The quick acting, silent alert vibrator activates
when a metallic target has been detected.
Screw-on Battery Cover
Makes changing the single 9V battery quick and
easy. No tools required. Battery terminal access
holes are keyed to avoid improper installation of
the 9V battery.

OPERATING INSTRUCTIONS
Turn the detector ON by pressing the “ON /
OFF” button. Note: The Green LED will light.
During operation, the Garrett THD will only detect
metal when the detector is in motion. Scan
within approximately one inch of the person being
inspected. Vibration will be felt and the Red LED
alert light will illuminate when metal is detected
anywhere within the detector’s detection area.
Operation is completely automatic, no retuning or
adjusting is ever necessary. Ferrous, non-ferrous
and stainless steel metals will be detected. To
scan feet and ankles, “sweep” the Garrett THD
perpendicularly and approximately one to two
inches above the floor or ground.

SERVICE INFORMATION
Battery Replacement
The Green LED light alert will change to Amber
when the battery is low and needs to be replaced.
Unscrew the battery cover, tilt the detector and
the battery will slip out. Replace with new 9V
battery; the battery compartment is keyed to only
accept battery contact in the proper position. If
a 9V battery is improperly installed, no circuitry
damage will occur. However, it is important to
observe the polarity of the battery and the THD
battery compartment to ensure optimum opera-
tion. Never force the cover to close.
Remove the battery when the detector is to be
stored for more than 30 days.
Factory Service
Pack the detector carefully and include com-
plete details concerning the problem, as well as
company name, contact person, address and
telephone number.
