• To avoid surprises, remember that studs or joists are
normally spaced 16 or 24 in. (41 or 61 cm) apart
and are 1½ in. (38 mm) in width. Anything closer
together or a different width may not be a
stud, joist, or firebreak.
Always turn off power when working near
electrical wires.
SCANNING DIFFERENT SURFACES
Freshly painted walls: May take one week or
longer to dry after application.
Wallpaper: The StudSensor
™
70 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.
Extremely 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. Calibrate,
with cardboard in place,
in High Sensitivity mode.
Wood flooring,
subflooring, or
gypsum drywall over plywood sheathing: Use
the High Sensitivity mode and move the tool slowly.
Lath & plaster: Due to irregularities in plaster
thickness, this tool is not recommended for use on
lath & plaster.
StudSensor
™
70 cannot scan for wood studs
and joists through concrete, carpeting and pad.
In Stud Scan mode, the StudSensor
™
70 will NOT
be able to scan through dense materials such as
glass, ceramic tile, and foil.
FOLLOW THESE INSTRUCTIONS MAY RESULT IN
ELECTRIC SHOCK, FIRE, AND/OR SERIOUS INJURY
OR PROPERTY DAMAGE.
Always turn off power when working near
electrical wires.
8. CHANGING MARKER TIPS
Removal: Pull and
hold the MARK
button to fully
extend the marker
tip. Grasp the
marker and pull it
off the marker post.
Replace: Pull and hold the MARK button to fully
extend the marker post. Push the new marker onto
the marker post.
Note: Two spare markers are stored in the battery
compartment. Additional marker tips can be
ordered from Zircon Customer Service at
1-800-245-9265.
Electrical field locators may
not detect live AC wires
if wires are more than 2 in. (51 mm) from the
scanned surface, in concrete, encased in conduit,
present behind a plywood shear wall or metallic
wall covering, or if moisture is present in the
environment or scanned surface.
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 POWER, GAS, AND WATER SUPPLIES
BEFORE PENETRATING A SURFACE. FAILURE TO
Note: Sensing depth and accuracy can vary due
to moisture, content of materials, wall texture,
and paint. Indoor use only.
Do not rely exclusively
on the detector to locate
items behind the scanned surface. Use other
information sources to help locate items before
penetrating the surface. Such additional sources
include construction plans, visible points of
entry of pipes and wiring into walls, such as in a
basement, and in standard 16 and 24 in. (41 and
61 cm) stud spacing practices.
3. TURNING ON/CALIBRATING THE TOOL
Place StudSensor
™
70 flat against the wall, then
press and hold the Power button. Upon completion of
calibration, the SpotLite
®
Pointing System and buzzer
will momentarily activate and the tool will begin
continuous measurements.
Note: It is important to wait for calibration to
complete (1–2 seconds) before moving the scanner.
ACT
™
(Auto Correcting Technology):
During scanning, the tool will provisionally
recalibrate itself when needed. This recalibration is
usually transparent and no indication is made.

1. INSTALLING THE BATTERY
Press battery door
release in with your
finger or a coin and
lift up to remove
door.
Place a brand
new 9V alkaline
battery into the
compartment and
press into place.
Replace battery
door and snap shut.
2. OPERATING TIPS
For optimum scanning results, it is important to
properly hold StudSensor
™
70 and move slowly
when scanning. The following tips will provide more
accurate scanning results:
• Keep the tool flat against the wall and do not
rock or tilt the tool when slowly sliding across the
surface being scanned.
• Avoid placing your other hand, or any other part of
your body, on the surface being scanned. This will
interfere with the tool’s performance.
• If you're receiving erratic scanning results, it may be
a result of humidity, moisture within the wall cavity
or drywall, or recently applied paint or wallpaper that
hasn't fully dried. While the moisture may not always
be visible, it will interfere with the tool's sensors.
Please allow a few days for the wall to dry out.
• 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.

besides studs.
You suspect
electrical wires, but
do not detect any.
Area of voltage
detection is too large.
• Tool not flat against wall.
• Tool tilted or lifted during scan. (All these factors affect
proper calibration.)
• Scanning surface is too dense or too wet for unit to operate.
• Electrical wiring and metal or plastic pipes may be near or
touching back surface of wall.
• Wires are shielded by metal conduit, a braided wire layer, behind
metallic wall coverings, plywood shear wall, or other dense material.
• Wires may not be live.
• Wires deeper than 2 in. (51 mm) from surface might not
be detected.
• Voltage detection can spread on drywall as much as 12 in. (30 cm)
from each side of an actual electrical wire.
• When scanning an uneven surface, place thin cardboard on the surface to be scanned and scan over
the cardboard in High Sensitivity mode.
• Grasp the handle with your thumb on one side and your fingers on the other side, not touching the
surface being scanned or the scanning head of the tool.
• Hold the tool straight up and down, parallel to the studs, and do not rotate the tool.
• If you are using tool on a recently taped, painted, or wallpapered wall, allow time to dry and try again.
• While tool is still on, quickly release and re-press the Power button to enter High Sensitivity mode.
• Check for other studs equally spaced to either side 12, 16, or 24 in. (30, 41, or 61 cm) apart or check for
the same stud at several places directly above or below the first finding. Studs will run straight up and
down from floor to ceiling while pipes may change direction.
• A stud reading would measure approximately
1½ in. (38 mm) apart from each edge; anything larger or
smaller is most likely not a stud if not near a door or window.
• Use extra caution if the area has plywood, thick wood backing behind drywall, or thicker than normal walls.
• If a switch controls an outlet, make sure it is ON for detection, but turned off when working near
electrical wires.
Use CAUTION when nailing, sawing, or drilling into walls, floors, and ceilings where these items
may exist.
• To narrow detection, turn tool off and on again at the edge of where wire was detected and scan again.

4. FINDING A STUD
Always start with the scanner placed flat against the
wall, then press the Power button. Wait for beep to
confirm calibration has completed before moving tool.
Slowly slide tool across
surface. EDGE LED will
illuminate, indicating
location of the stud edge.
Continue sliding
tool. When the
center of the stud is
located, the buzzer
will sound, and both
the CENTER LED
and the SpotLite
®
will illuminate.
In cases of deeper studs (thicker walls) when the
center of the stud is
located only the three
middle and CENTER
LEDs will illuminate.
If you still can’t locate
a stud, try the next step.
Note: The tool may detect other objects behind
the wall such as pipes and conduit. See Section 2:
Operating Tips for ways to confirm that you found
a stud.
5. DIFFICULTY LOCATING A STUD?
TRY HIGH SENSITIVITY MODE
If you have difficulty locating a stud after following
Step 4, it could be that the stud is deep (the walls
are thick). With the tool still placed flat against the
wall and turned on, quickly (within one second)
release and re-press the Power Button. The scanner
will enter the High
Sensitivity Mode and
the DEEP LED will flash
continuously. Center of
a very deep stud will be
indicated by the three
middle LEDs illuminating.
6. MARKING THE CENTER OF THE STUD
Once an object is
located, mark the
location by gently
pulling down the
MARK button with
your fingertip. A
pencil point will
extend from the front
of the handle, placing
a short, erasable line
on the wall.

• Grasp the handle with your thumb on one side
and your fingers on the other side. Make sure your
fingertips are resting on or above the running board
and not touching the surface being scanned or the
scanning head of the tool.
• Hold the tool straight up and down, parallel to the
studs, and do not rotate the tool.

• No studs in that area.
• No, or low, battery in tool.
• Move tool several inches (12–13 cm), to the left or right and start again.
• Replace with brand new 9V alkaline battery.
