scanning results:
• Grasp the handle with your thumb on one side
and your fingers on the other side. Make sure your
fingertips are resting on the tool 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.

Note: The tool may detect other objects behind the wall
such as pipes and conduit. See Section 2: Operating Tips
Zircon's WireWarning
for ways to confirm that you found a stud.
When live AC voltage is detected, the AC WireWarning
indicator will appear in the display.

• 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,

• To avoid surprises, remember that studs or joists are
normally spaced 16 or 24 in. (41 or 61 cm) apart
and are 1 1 ⁄ in. (38 mm) in width. Anything closer

WARNING
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
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.
FCC Part 15 Class B Registration Warning
This device complies with Part 15 of FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
SCANNING DIFFERENT SURFACES
Freshly painted walls: May take one week or longer
to dry after application.
Wallpaper: The StudSensor ™ L70 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 DeepScan mode.
®
Wood flooring, subflooring, or
gypsum drywall over plywood
sheathing: Use the DeepScan
®
mode and move the tool slowly.
The Signal Strength Indicator may
only display 1 or 2 bars when the
tool locates a stud through thick
surfaces.
Lath & plaster: Due to
irregularities in plaster thickness,
this tool is not recommended for
use on lath & plaster.
StudSensor ™ L70 cannot scan for
wood studs and joists through
concrete or carpeting and pad.
In StudScan mode, the StudSensor
able to scan through dense materials such as glass,
ceramic tile, and foil.
Note: Sensing depth and accuracy can vary due to
moisture, content of materials, wall texture, and paint.

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 ™ L70 flat against the wall, then press
and hold the Power button. The LCD will illuminate
and display all icons until calibration is complete. Upon
completion of calibration, the SpotLite Pointer 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. If an arrow icon illuminates,
the tool was calibrated near or over a stud and then
moved away. The arrow indicates the direction of the
missed stud.

• When scanning an uneven surface, place thin cardboard on the surface to be scanned and scan over
the cardboard in DeepScan
• 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 unit on a recently taped, painted, or wallpapered wall, allow time to dry and try again.
• While unit is still on, quickly release and re-press the Power button to enter DeepScan
• 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.

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.
• Replace with brand new alkaline 9 V battery.
