SCANNING DIFFERENT SURFACES
Freshly painted walls: May take one week or
longer to dry after application.
Wallpaper: The StudSensor
™
i 65 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. 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
™
i 65 cannot scan for wood studs and
joists through carpeting and pad. In Stud Scan
mode, the StudSensor
™
i 65 will NOT be 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.
ELECTRIC SHOCK, FIRE, AND/OR SERIOUS INJURY
OR PROPERTY DAMAGE.
Always turn off power when working near
electrical wires.
Electrical field locators may
not detect live AC wires if
wires are more than 51 mm from the scanned
surface, 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
FOLLOW THESE INSTRUCTIONS MAY RESULT IN
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 41 cm and 61 cm
stud spacing practices.
3. TURNING ON/CALIBRATING THE TOOL
Place StudSensor
™
i 65 flat against the wall, then
press and hold the Power button. The LCD will
display all icons until calibration is complete. 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. 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.
StudSensor
™
i65 OneStep
™
Centre-Finding Stud Finder
The Zircon StudSensor
™
i 65 OneStep
™
detects both
the centre and edges of wood and metal studs
and joists in walls, floors, and ceilings in one step.
It features a durable high-impact case and the
patented SpotLite
®
Pointing System.

1. INSTALLING THE BATTERY
Press battery door release in with your finger or a
coin and lift up to remove door.
Place a new 9 V 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
™
i 65 and move slowly
when scanning. The following tips will provide more
accurate 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 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.
• 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.
• To avoid surprises, remember that studs or joists
are normally spaced 41 cm or 61 cm apart and are
38–45 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.

All LCD segments
turn on at the same
time and the unit
beeps continuously.
Detects other objects
besides studs.
You suspect
electrical wires, but
do not detect any.
Area of voltage
detection is too large.
• Unit not flat against wall.
• Unit 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 51 mm from surface might not be detected.
• Voltage detection can spread on drywall as much as 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 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 High Sensitivity mode.
• Check for other studs equally spaced to either side (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 38–45 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 unit off and on again at the edge of where wire was detected and scan again.

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 unit still placed flat against the wall
and turned on, quickly (within one second) release
and re-press the Power button. The Stud Scan mode
indication will flash continuously, indicating that the
tool has entered High
Sensitivity mode. The
centre of a very deep
stud will be indicated
by the four middle
bars illuminating.
6. MARKING THE CENTRE OF THE STUD
Once an object is
located, mark the
location where the
SpotLite
®
Pointing
System illuminates.
This is the centre of
the stud.
