Two scanning modes:
• StudScan
locates center and edges of stud (wood or
metal) up to
3
⁄
4
"
(19 mm) deep
• DeepScan
locates center and edges of stud up to
1
1
⁄
2
"
(38 mm) deep
WireWarning
Detection
automatically detects and
alerts for live AC (alternating current) wires in both modes.
When AC voltage is detected, WireWarning Detection
Indicator shows on the display.
INSTALL 9-VOLT BATTERY
Always use a new alkaline
battery
with a valid extended expiration date.
Match battery direction to image
inside of battery cavity.
Low Battery Indicator
will flash
when battery charge is too low for
scanner to function properly.
WARNING
Do not rely exclusively on the
scanner 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.
DEEPSCAN MODE
DeepScan Mode will detect studs
up to 1
1
⁄
2
"
(38 mm) deep, or twice
the depth of StudScan.
To activate DeepScan Mode:
1.
Place the tool flat against
the wall.
2.
Quickly press the Power Button
twice, and hold it down after the
second press. The DeepScan Mode
Indicator will light. (
Figure G
)
3.
To find a stud, follow steps 2 and 3 under
FIND A STUD.
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.
WIREWARNING
DETECTION
The Zircon
®
WireWarning Detection
feature works continuously in
both modes. When live AC voltage
is detected, the WireWarning
Detection Indicator shows. If
scanning begins over a live AC wire,
the indicator will flash continuously.
(
Figure H
)
Use extreme caution under these circumstances,
or whenever live AC wiring is present.
WARNING
THE SCANNER MAY NOT DETECT
LIVE CURRENT IF WIRES ARE MORE
THAN 2" (50 mm) BELOW 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.
POWER UP
To activate tool, press and hold Power Button.
If button is not pressed and held, unit shuts off.
FIND A STUD
For best results, hold the tool as
shown (
Figure A
) and move slowly
when scanning.
Do not touch
the surface during calibration
or scan.
1.
Hold tool flat against wall,
then press and hold Power Button.
In 1–2 seconds, the unit will
calibrate. A short beep confirms
that calibration is complete.
DO NOT MOVE TOOL
DURING CALIBRATION.
2.
While holding down the
Power Button, slide the tool slowly
along the wall. When tool finds
the edge of a stud, EDGE displays.
(
Figure B
)
3.
Continue sliding. When tool
finds the center of a stud, CENTER
displays, light illuminates, 3 bars
show signal strength, and a
buzzer sounds. (
Figure C
)
NOTE: If only two signal bars
show (Figure D), stud may be
too deep. Switch to DeepScan
Mode, and repeat scan.
4.
Use the SpotLite Pointer to
mark the location of the center of
the stud. (
Figure E
)
Tool automatically recalibrates
when in use. If an arrow shows
(
Figure F
), the tool was calibrated
too close to a stud, then moved
away. Arrow indicates the direction
to the stud. This is
ACT (Auto
Correcting Technology)
.
WORKING WITH DIFFERENT MATERIALS
Wallpaper
This 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
Due to irregularities in plaster
thickness, this tool is not recommended for use on 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. The Signal Strength Indicator may
only display one or two bars when the tool locates a stud
through a thick surface.
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,
the 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 and joists
are normally spaced 16 or 24" (40 or
60 cm) apart, and are 1
1
⁄
2
" (38 mm) wide. Anything closer
together, or of a different width, may not be a stud or joist.

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 EVERYTHING DETECTED IS A STUD.
- Always use a new alkaline battery with a valid extended expiration date. Match battery direction to image inside of
battery cavity.
- Do not rely exclusively on the scanner 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 and wiring into walls such as
in a basement, and standard stud-spacing practices.
- Always start your scan in StudScan Mode which scans through surfaces up to
3
⁄
4
" (19 mm) deep. Scanning in
DeepScan
®
Mode may detect an object further behind the wall that may or may not be a stud.
- 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, like a stud would.
- Readings should always be consistent and repeatable.
- Zircon stud finders are recommended for interior use only.
- Studs normally run from floor to ceiling, except above and below windows, and above doors.
- Other objects commonly contained in walls, floors, or ceilings are water pipes, 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.
- Always turn off power when working near electrical wires.
- Depending on the proximity of electrical wiring or pipes to the wall surface, the scanner 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 and joists are normally spaced 16 or 24" (40 or 60 cm) apart, 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 or joist.

TROUBLESHOOTING & CONSTRUCTION TIPS
SITUATION
LIKELY CAUSE
SOLUTION
All display elements
turn on at the same
time and the tool
beeps continuously.
Tool not held flat
against wall.
• Hold the tool with your thumb on one side and your fingers on the other
side. Do not touch the surface being scanned or the scanning head of the tool.
• Move the tool straight up and down, parallel to the studs. Do not rotate
the tool.
Tool tilted or lifted
during scan.
• When scanning an uneven surface, place thin cardboard on the surface
to be scanned and scan over the cardboard in DeepScan Mode.
• With tool on, quickly release and re-press the Power Button to enter
DeepScan Mode.
Scanning surface is too
dense or too wet for
tool to operate.
If you are using tool on a recently taped, painted, or wallpapered wall, allow
time to dry and try again.
Tool detects objects
other than studs,
or finds more studs
than should be there.
Electrical wiring and
metal or plastic pipes
may be near to or
touching the back of
the wall surface.
Check for other studs equally spaced to either side at 12, 16 or 24
"
(30, 40, or 60 cm), or check for the same stud at spots directly above or below
the first scan area. Studs will run straight up and down, from floor to ceiling,
while pipes may change direction. Standard studs measure approximately 1
1
⁄
2
"
(38 mm) between edges. Anything larger or smaller is likely not a stud (unless
near door or window).
Area of voltage
detection is too
large.
Voltage detection can
spread on drywall by as
much as 12
"
(30 cm) on
each side of the wire.
Narrow the scan detection:
1.
Turn tool off.
2.
Turn it on again at the edge of
where the wire was first detected.
3.
Repeat scan.
You suspect
electrical wires,
but WireWarning
Detection does
not alert.
Wires are shielded
by a metal conduit,
braided wire or
metallic wall covering.
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 deeper than
2
"
(50 mm) from the
surface might not
be detected.
See above.
Wires may not be live.
Plug a lamp into the outlet and turn it on to test whether wires are live.
Low Battery Indicator
flashes and tool does
not operate.
Low battery.
Install new 9-volt alkaline battery with valid extended expiration date.
