Featuring Revolutionary Target Control
®
(TC
™
) Technology
TC
™
technology is tuned to find wood studs while
filtering out (rejecting) metallic or low signal false
positive objects such as plumbing, conduit, straps,
brackets, or plastic water pipes. With TC
™
mode,
users can utilize
Trust but Verify
technique to
help identify “safe-to-drill” zones between adjacent
drywall screws, nails, and protector plates.
Two scanning modes:
•
Target Control
®
(TC
™
)
locates center, edges,
and direction of wood studs (while ignoring
metal) up to
3
⁄
4
" (19 mm) deep.
LCD will be
backlit with a blue light.
In TC
™
mode,
LoLevel
™
Indicator indicates low (weak) signal
objects, such as plastic water pipes, plastic sewer
drains, or studs deeper than
3
⁄
4
" (19 mm). When
compared to stud signals, the LoLevel
™
Indicator
may help differentiate studs from false positives.
•
StudScan
locates center, edges, and direction of
both wood and metal studs up to
3
⁄
4
" (19 mm) deep.
LCD will not be backlit in this mode.
In StudScan mode, the Signal Strength Indicator
uses the same icon as the LoLevel
™
Indicator.
When TC
™
is off, a strong signal is indicated by
full signal strength bars.
WIREWARNING
®
DETECTION
The Zircon
®
WireWarning
®
Detection
continuously detects and alerts for live,
unshielded AC (alternating current) wires in
both modes. When live AC voltage is detected,
warning indicator appears until tool is
moved sufficiently away from the live wire.
When calibration begins over an AC wire,
AC icon will flash.
Use extreme caution under these
circumstances or whenever live AC wiring
is present.
FIND A STUD IN STUDSCAN MODE
(TC
™
OFF)
1.
Hold tool flat against wall,
press Power
Button, release it, then press it again,
holding it down the second time. Device will
calibrate in 1–2 seconds. A short beep confirms that
calibration is complete. If a calibration error occurs,
all icons will flash continuously.
NOTE:
Tool is in StudScan mode (TC
™
off)
when LCD backlight is off.
When TC
™
mode
is off, metal objects may be indicated as a stud
and Signal Strength Indicator will have steady
strength bars.
DO NOT MOVE TOOL DURING CALIBRATION.
2.
While holding down Power Button, slide tool
slowly along wall. When tool finds edge of a stud,
Edge Indicator shows.
3.
Continue sliding.
When tool finds center of
a stud, Crosshairs turn on,
SpotLite
®
illuminates, and a
beep sounds. (

WARNING
DO NOT ASSUME THERE ARE NO
LIVE ELECTRICAL WIRES IN
THE WALL. DO NOT TAKE ACTIONS THAT
COULD BE DANGEROUS IF THE WALL
CONTAINS A LIVE ELECTRICAL WIRE.
ALWAYS TURN OFF THE ELECTRICAL, GAS,
AND WATER SUPPLIES BEFORE PENETRATING
A SURFACE. FAILURE TO FOLLOW THESE
INSTRUCTIONS MAY RESULT IN ELECTRIC
SHOCK, FIRE, AND/OR SERIOUS INJURY OR
PROPERTY DAMAGE.
WARNING
Tool may not detect AC activity if
wires are more than 2" (50 mm)
behind the scanned surface, in concrete,
encased in conduit, behind a plywood shear
wall or metallic wall covering, or if moisture is
present in the environment or scanned surface.
INSTALL 9-VOLT BATTERY
Always use a new 9V alkaline battery with an
extended expiration date at least 3 years beyond
current date. Match battery direction to image
inside battery cavity.
WARNING
Do not rely exclusively on tool
to locate items behind a surface.
Use other information to help locate items
before penetrating the surface,
including construction plans, visible points
of entry of pipes and wiring into walls,
such as in a basement, and standard
stud-spacing practices.
POWER UP
To activate tool, press and hold Power Button.
The default mode at power up is TC
™
. Device shuts
off 1–2 seconds after Power Button is released.

4.
Tool automatically
recalibrates when in use. If the
two ACT
™
arrows appear
on LCD, tool was calibrated
over a stud, then moved away.
This is ACT
™
(Auto Correcting Technology) in action.
NOTE:
LoLevel
™
Indicator will display rapidly
cascading bars when device senses a sustained
weak signal, indicating a false positive object may
be present.
5.
Use the
Trust but Verify
technique for
finding drywall screws or nails up and down stud
to confirm that you have located a wood stud.
Other objects, such as plastic plumbing pipes,
do not contain nails or drywall screws.
(See important note under BEFORE YOU BEGIN
for more information on this procedure.)
WORKING WITH DIFFERENT MATERIALS
Wallpaper
Tool functions normally on walls
covered with wallpaper or fabric, unless the
materials are metallic foil, contain metallic fibers,
or are still wet after application. Wallpaper may need
to dry for several weeks after application.
Freshly painted walls
It may take a week or
longer to dry after application.
Lath and plaster
This tool is not designed to scan
over lath and plaster.
Highly textured walls or acoustic ceilings
This tool is not designed to scan over highly
textured walls or acoustic ceilings.
Wood flooring, subflooring, or gypsum
drywall over plywood sheathing
Tool cannot
scan for wood studs and joists through
these materials, or through carpet and padding.
NOTE:
Sensing depth and accuracy can
vary depending on scanning environment
conditions such as mineral content,
moisture, texture, and consistency of the
wall materials.
Electrical wiring and pipes
Depending on
the proximity of electrical wiring or pipes to the
wall surface, tool may detect them in the same
manner as studs.
Caution should always be used when nailing,
cutting, or drilling in walls, floors, and ceilings
that may contain these items.
Studs
Studs are normally spaced 16" or 24"
(40 cm or 60 cm) apart on center and are
1
1
⁄
2
" (38 mm) wide.
Anything closer together, or of a different width,
may not be a stud.

STUD FINDERS WORK BY SENSING DENSITY CHANGES BEHIND THE WALL. OTHER OBJECTS
CAN BE DETECTED, ESPECIALLY IF THEY ARE VERY CLOSE TO THE WALL.
DO NOT ASSUME THAT
EVERYTHING DETECTED IS A STUD.
- Always use a new 9V alkaline battery with an extended expiration date at least 3 years beyond the
current date. Match battery direction to the image inside of battery cavity.
- Do not rely exclusively on the tool to locate items behind a surface. Use other information to help locate
such items before penetrating the surface, including construction plans, visible points of entry of pipes,
wiring into walls such as in a basement, and standard stud-spacing practices.
- Always start your scan in Target Control
®
(TC
™
) mode, which scans through standard single layer drywall
up to
3
⁄
4
" (19 mm) deep.
- Always scan for studs at several different heights on the wall and mark the location of every target
indicated by the stud finder. This is called “mapping the wall.” Pipes and other objects will likely not give
consistent readings from floor to ceiling, as a stud would.
- Studs normally run from floor to ceiling, except above and below windows and above doors.
- Readings should always be consistent and repeatable.
- Zircon
®
stud finders are recommended for interior use only.
- Other objects commonly contained in walls, floors, or ceilings are water pipes (plastic and metal),
gas lines, firestops, and electrical wiring.
- Sensing depth and accuracy can vary depending on scanning environment conditions, such as
mineral content, moisture, texture, and consistency of the wall materials.
- Depending on the proximity of electrical wiring or pipes to the wall surface, tool may detect them in
the same manner as studs.
Caution should always be used when nailing, cutting, or drilling in walls, floors, and ceilings
that could contain these items. Use extreme caution under these circumstances or whenever
live AC wiring is present.
- Studs are normally spaced 16" or 24" (40 cm or 60 cm) apart on center, are normally 1
1
⁄
2
" (38 mm) wide,
and may be separated by firestops. Anything closer together, or of a different width, may not be a stud.
IMPORTANT:
Trust but Verify
is a technique that can help indicate “safe-to-drill” zones to minimize
hitting existing metals on a stud, such as nails, screws, and protector plates. When the Crosshairs show
in TC
™
mode, run tool vertically up and down the stud. The stud indicators (Crosshairs, Edge Indicators,
Target Indicator Bars, Target Spotlight, and SpotLite
®
Pointer) will all turn off over screws and other metal,
then turn on again when the stud is free from metal. The "safe-to-drill" zones are typically between
adjacent drywall screws, nails, or protector plates, assuming the builder properly installed metal protector
plates on the stud, and over plumbing and electrical. If stud indicators do not disappear when running
vertically up and down the object in TC
™
mode, the absence of drywall screws, nails, and protector plates
indicates this could be a non-metallic object such as plastic plumbing or PEX tubing, and should not be
mistaken for a stud.

TROUBLESHOOTING & CONSTRUCTION TIPS
SITUATION
LIKELY CAUSE
SOLUTION
Tool detects objects
other than studs in
StudScan mode or finds
more objects that look
like studs than should
be there.
Electrical wiring
and metal or plastic
pipes may be near,
or touching,
the back of the
wall surface.
• Check for other studs equally spaced to either side at
16" or 24" (40 cm or 60 cm) and check for the same stud
at spots directly above or below the first scan area.
• Standard studs measure approximately 1
1
⁄
2
" (38 mm)
between edges. Anything smaller or larger is likely not a stud
(unless near a door or window).
Studs are continuously
detected near windows
and doors.
Multiple studs are
in use.
Double and triple studs are sometimes used around doors
and windows. Headers are used above them. Detect outer
edges so you know where to begin.
Electrical wires suspected
but WireWarning
®
Detection does not alert.
Wires deeper than
2" (50 mm) from
the surface might
not be detected.
If there is an outlet switch, turn it to ON position
while scanning, but turn OFF when working near the wires.
Use extra caution if the area has plywood, thick wood backing
behind drywall, or walls that are thicker than normal.
Wires may not
be live.
Plug a lamp into the outlet and turn it on to test whether wires
are live.
Low Battery Indicator on. Low battery.
Install a new 9V alkaline battery with an extended expiration date.
