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.
Three 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 pale
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.
•
DeepScan
®
locates center, edges, and direction of
studs (wood and metal) up to 1
1
⁄
2
" (38 mm) deep.
LCD will be backlit with a green light.
NOTE:
TC
™
and StudScan use the same switch setting but
function differently. StudScan detects both wood and metal
studs during scanning, while TC
™
detects only wood studs
and ignores metal. You can distinguish between the two
modes by the pale blue backlight on LCD in TC
™
mode.
StudScan is not backlit.
MetalliWarning
™
Indicator
will
display when metal is detected or dangerously close in TC
™
,
StudScan, and DeepScan
®
modes.
WIREWARNING
®
DETECTION
The Zircon
®
WireWarning
®
Detection
continuously detects
and alerts for live, unshielded AC (alternating current) wires in
any mode. When live AC voltage is detected, warning indicator
appears and screen starts flashing red until tool is moved
sufficiently away from the live wire. When calibration
begins over an AC wire in any mode, AC icon will flash.
Use extreme caution under these circumstances or
whenever live AC wiring is present.

for use with thicker walls. It can detect studs up to
1
1
⁄
2
" (38 mm) deep.
1.
Set mode to DeepScan
®
.
2.
Repeat steps 2–4 under STUDSCAN MODE section.
NOTE:
When scanning on thicker surfaces, device may
not find edges on surfaces thicker than
3
⁄
4
" (19 mm).
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.
SELECT MODE / POWER UP

)
5.
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.
6.
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.)
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.
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
When scanning a ceiling or wall with an uneven surface,
place thin cardboard on the surface to be scanned and
scan over the cardboard in DeepScan
®
mode.
Wood flooring, subflooring, or gypsum drywall
over plywood sheathing
Use DeepScan
®
mode and
move the tool slowly. This tool cannot scan for wood
studs and joists 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.

BEFORE YOU BEGIN
ZIRCON
®
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 none detected.
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.
LCD screen flashes
continuously when trying
to find stud.
Tool is experiencing
oversaturation of
exposure to metal.
Switch to TC
™
or StudScan mode to lessen sensitivity to metal.
NOTE:
Tool may not beep over studs 1" (25 mm) or deeper
when doing this.
Low Battery Indicator on.
Low battery.
Install a new 9V alkaline battery with an extended expiration date.
