Wood Stud SuperScan®

Advanced Stud Finder with Target Control® + FILTERz™ Technology

BEFORE YOU BEGIN

Always map your work area prior to cutting or drilling.
– Always use two new AA (1.5 V) alkaline batteries 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 Auto or Edge mode, which scans for wood studs through surfaces up to ¾” (19 mm) deep. DeepScan® mode may detect objects further behind
the wall that may or may not be a stud.
– Studs are normally spaced 16″ or 24″ (40 cm or 60 cm) apart on center, are normally 1½” (38 mm) wide, and may be separated by firestops. Anything closer together,
or of a different width, 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 scans for wood and metal studs and 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.

ABOUT WOOD STUD SUPERSCAN® ADVANCED STUD FINDER

Designed to locate wood studs and avoid metallic objects, such as plumbing,
conduit, straps, brackets, screws, protector plates, or ducts hiding in the wall,
patented Target Control® (TC™) technology analyzes complex data streams while
+ FILTERz™ technology helps avoid low signal-strength, non-metallic targets,
such as plastic pipe, PEX tubing, wiring, and more. TC™ is enabled in
Auto and Edge modes only. TC™ is not enabled in DeepScan® mode.

Three scan modes:

Auto Mode locates the center and edges of wood studs up to ¾” (19 mm) deep.
TC™ technology is always engaged in this mode and will filter out metal.
The Left Edge, Center, and Right Edge Indicators will all light green to designate
tool is in Auto mode.
Edge Mode locates the edges of wood studs up to ¾” (19 mm) deep.
TC™ technology is always engaged in this mode and will filter out metal.
Both Edge Indicators will light green to designate tool is in Edge mode.
DeepScan® Mode locates the center of wood and metal studs up to
1½” (38 mm) deep. TC™ technology is off in this mode and will detect metal.
Center Indicator will light green to designate the tool is in DeepScan® mode.

WIREWARNING® DETECTION

WireWarning® Detection continuously detects and alerts for live,
unshielded AC (alternating current) wires in all 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.

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.

METALLIWARNING® INDICATION

In Auto and Edge modes, when metal is detected, the Stop Indicator will display
a solid red light (known as MetalliWarning® Indication).

LOLEVEL® INDICATION

In Auto and Edge modes, when tool senses a sustained weak signal, the Stop
Indicator will flash red. A weak (low) signal may indicate other objects are present,
such as plastic water pipes, PEX tubing, and plastic sewer drains.

INSTALL AA BATTERIES

Always use two new AA (1.5 V) alkaline batteries 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 / SELECT MODE

Press and release the Power Button to turn tool on. Do NOT hold Power Button
down while scanning. Tool will calibrate as confirmed by a simultaneous flicker of
the SpotLite® Pointer, all indicators briefly lighting, and haptic vibration. To change
between modes, press the Power Button repeatedly until reaching the desired mode.
Mode sequence is as follows: Auto, Edge, DeepScan® modes.

Tool will power off 3 minutes after the Power Button is released or when the tool is
lifted from the surface after calibration is complete. To manually power off the tool,
press the Power Button down 2 seconds. The tool will power back on in the mode
last engaged.

SCANNING TECHNIQUE

For best results, hold tool flat against the surface, with thumb and index fingers
placed on the pivot pinch grip and Power Button. Holding the tool incorrectly can
cause inaccurate readings. Move slowly when scanning. Do not touch wall surface
with either hand during calibration or scanning.

SCAN IN AUTO MODE

Use Auto mode to find the center and edges of wood studs
up to ¾” (19 mm) deep.
1. Hold tool flat against wall, then press and release
Power Button. Toggle mode by pressing then releasing Power
Button repeatedly until the Center and Edge Indicators light
solid green (Figure A). Unit will calibrate in 1–2 seconds.
Do not move tool during calibration. Proper calibration
is confirmed by a simultaneous flicker of SpotLite® Pointer,
all indicators briefly lighting, and haptic vibration.
2. Slide tool slowly along wall. When tool finds the edge
of a stud, SpotLite® Pointer illuminates, Edge Indicator
flashes green, Target Indicator Arrow lights solid green,
and a haptic vibration occurs. (Figure B)
3. Continue sliding. When tool finds the center of a stud,
SpotLite® Pointer illuminates, Center Indicator flashes green,
Target Arrow Indicator lights solid green, and a haptic
vibration occurs (Figure C). Mark spot where stud center
was found.
4. Continue scanning past to find other stud edge.
The width of a stud is typically 1½” (38 mm).
Trust but Verify is a technique that can help minimize
hitting existing metals on a stud, such as nails, screws,
and protector plates. Once you have found the center of the
stud in Auto mode, continue to run the tool vertically up
and down the stud. The Stop Indicator light will turn on over
screws or other metal, then turn off again when the stud
is free from metal. If metal protector plates are properly installed
over plumbing and electrical, the “safe-to-drill” zones are typically between adjacent
drywall screws, nails, or protector plates. If the Stop Indicator stays continuously on
when running vertically up and down the object, it could be a metal pipe and should
not be mistaken for a stud.

SCAN IN EDGE MODE

Use Edge mode to find the edges of wood studs up to ¾” (19 mm) deep.
See SCANNING TECHNIQUE for best results.
1. Hold tool flat against wall, then press and release Power
Button. Toggle mode by pressing then releasing Power Button
repeatedly until only both Edge Indicators light solid green
(Figure D). Wait for the tool to calibrate in 1–2 seconds.
Do not move tool during calibration. Calibration is
confirmed by a simultaneous flicker of SpotLite® Pointer,
all indicators briefly lighting, and a haptic vibration.
2. Slide tool slowly along wall, keeping the Power
Button pressed. When tool finds the edge of a stud,
SpotLite® Pointer illuminates, Edge Indicator flashes green,
Target Arrow Indicator lights solid green, and a haptic
vibration occurs (Figure E). Mark stud edge.
3. Continue sliding. When tool scans over the object,
the Target Arrow Indicator will light solid green to indicate
its presence only and is not indicating stud center.
4. Continue sliding. When tool finds other stud edge,
SpotLite® Pointer illuminates, other Edge Indicator
flashes green, Target Arrow Indicator lights solid green,
and a haptic vibration occurs. Mark other stud edge

SCAN IN DEEPSCAN® MODE

DeepScan® mode locates the center of wood and metal studs through thicker walls
up to 1½” (38 mm) deep. See SCANNING TECHNIQUE for best results.
1. Hold tool flat against wall, then press and release
Power Button. Toggle mode by pressing then releasing Power
Button repeatedly until only the Center Indicator lights solid
green (Figure F). Wait for the tool to calibrate in 1–2 seconds.
Do not move tool during calibration. Calibration is
confirmed by a simultaneous flicker of SpotLite® Pointer,
all indicators briefly lighting, and a haptic vibration.
2. Slide tool slowly along wall. When tool finds center
of a wood or metal stud, SpotLite® Pointer illuminates,
Center Indicator flashes green, Target Arrow Indicator lights
solid green, and a haptic vibration occurs. Mark stud center.
NOTE: In DeepScan® mode, the Stop Indicator will flash red when metal is detected.
To confirm you have located a wood stud, use the Trust but Verify technique to find
drywall screws or nails up and down stud. Other objects, such as plastic plumbing
pipes, do not contain nails or drywall screws. A metal pipe or stud will give a
continuous metal reading indicated by the solid illuminated Stop Indicator.

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
Studs Studs are normally spaced 16″ or 24″ (40 cm or 60 cm) apart on center
and are ½” (38 mm) wide. Anything closer together, or of a different width, may not
be a stud.

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. For freshly painted
walls, it may take a week or longer to dry after application.

Lath and plaster 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.

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.
NOTE: Sensing depth and accuracy can vary depending on scanning
environment conditions such as mineral content, moisture, texture,
and consistency of the wall materials.

TROUBLESHOOTING & CONSTRUCTION TIPS

SITUATION

|

LIKELY CAUSE

|

SOLUTION

---|---|---

Tool detects objects other than studs during scanning or finds more objects that look like studs than should be there.

|

Objects 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 1½” (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.

Tool Indicators flash continuously when trying to find stud.

|

Scanner is experiencing oversaturation when scanning over a dense object.

|

Restart scan and recalibrate in a different location.

Low Battery Indicator on.

|

Low battery.
