Always turn off the power when working near

electrical wires.

WORKING WITH DIFFERENT MATERIALS

StudSensor

™

55 is for use on dry interior

walls only.

Note: Sensing depth and accuracy can vary due

to moisture, content of materials, wall texture,

and paint.

StudSensor

™

55 can scan effectively through most

sheet materials, including:

• Bare wood flooring (in DeepScan

mode)

• Linoleum on wood base

• Gypsum drywall over plywood sheathing

• Wallpapered walls (if dry)

• Textured ceilings if uniform thickness (place a thin

piece of cardboard on ceiling and scan over it to

avoid damage to texturing)

StudSensor

™

55 is not designed to scan materials

such as:

• Ceramic floor tile

• Carpeting and padding

• Wallpaper with metallic fibers

• Freshly painted walls that are still damp (may take

one week or longer to dry after application)

• Lath and plaster walls

• Foil covered insulation board

• Glass or any other dense material

3. SELECTING THE MODE

Move selector switch to the desired mode:

StudScan for finding wood or metal studs or

DeepScan

for finding studs behind walls more

than

⁄4 in. (19 mm) thick.

Unit will remain off if Power Button is not depressed.

4. FINDING A STUD

Always scan for studs with the scanner placed flat

against the wall. Move the mode switch to StudScan,

place the tool flat against the wall, then press and hold

the Power Button. Wait for beep to confirm calibration

has completed before moving scanner.

1. INSTALLING THE BATTERY

Push in the battery door

tab at the bottom of the

tool and open the door.

Insert a new 9V battery,

matching the positive (+)

and negative (-) terminals to

the icons printed on the back.

Snap the battery into place

and replace the door.

2. OPERATING TIPS

For optimum scanning results:

• Hold the tool straight up and down, parallel to the

studs, and do not rotate the tool.

• Keep tool flat against the wall and do not rock, tilt,

or press hard 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.

• 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 16 or 24 in. (41 or 61 cm) apart

and are 1

⁄2 in. (38 mm) in width. Anything closer

together or a different width may not be a stud,

joist, or firebreak.

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.

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.

Continue to hold

the Power Button,

then slowly slide unit

horizontally across

the wall, left or right.

As you begin to

approach a stud,

the outer Target

Indication Bars will

begin to turn on.

When the full Target

Indication Bars are first

displayed across the

display, the SpotLite

Pointer and Target

Spotlight shine, and a

steady tone sounds, you

have located the edge of

the stud. Mark this spot.

Without releasing the

Power Button, continue

scanning beyond the

marked spot until some

Target Indication Bars

turn off. Slide unit in

the reverse direction to

locate the other edge

of stud.

Mark this second

spot. Center of stud

is midway between

the two marks.

• On rough surfaces, place a thin piece of cardboard on

wall, scanning over it to help slide unit more smoothly.

• Keep hand at least 6 in. (15 cm) from unit while you

calibrate and scan. Hold unit with thumb and index

finger no higher than handgrips. Be careful not to

move your fingers after calibration.

• Always hold unit parallel to the stud and move it

perpendicular to the stud you’re trying to locate.

• If you are using unit on a recently taped, painted, or

wallpapered wall, allow time to dry and try again.

DETECTION

WireWarning

Detection works continuously in

StudScan and DeepScan

modes. When live AC voltage

is detected, the WireWarning

indicator will appear on

the display. If scanning begins over a live AC wire,

the WireWarning

indicator will flash continuously.

Use extreme caution in these circumstances or

whenever live AC is present.

Electrical field locators may

not detect live AC wires if

moisture is present in the wall, or if wires are

more than 2 in. (51 mm) from the scanned

surface, in plastic conduit or behind a plywood

shear wall or metallic wall covering.

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

ELECTRIC SHOCK, FIRE, AND/OR SERIOUS INJURY

OR PROPERTY DAMAGE.
