Featuring Revolutionary Target Control

 (TC

) Technology

TC

 technology is tuned to find wood studs while filtering out (rejecting) 

metallic or low signal false positive objects such as plumbing, conduit, 

straps, brackets, or plastic water pipes. With TC

 mode, users can utilize 

Trust but Verify

 technique to help identify “safe-to-drill” zones between 

adjacent drywall screws, nails, and protector plates.

Five scanning modes:

• 

Target Control

 (TC

)

 locates centre, edges, and direction of wood 

studs (while ignoring metal) up to 19 mm

b

deep. 

LCD will be backlit 

with a pale blue light.

 In TC

 mode, LoLevel

 Indicator indicates 

low (weak) signal objects, such as plastic water pipes, plastic sewer 

drains, or studs deeper than 19 mm. When compared to stud signals, 

the LoLevel

 Indicator may help differentiate studs from false positives.

• 

StudScan

 locates centre, edges, and direction of both wood and metal 

studs up to 19 mm deep. 

LCD will not be backlit in this mode.

 

In StudScan mode, the Signal Strength Indicator uses the same icon as 

the LoLevel

 Indicator. When

b

TC

 is off, a strong signal is indicated by 

full signal strength bars.

• 

DeepScan

 locates centre, edges, and direction of studs 

(wood and metal) up to 38 mm deep. 

LCD will be backlit with 

a green light.

• 

Metal Scan

 locates ferrous (magnetic) metal, such as steel, up to 

75 mm deep, and non-ferrous (non-magnetic) metal, such as copper, 

up to 38 mm deep. 

LCD will be backlit with a dark blue light.

• 

AC Scan

 locates live, unshielded AC wires behind drywall up to 50 mm 

deep. 

LCD will be backlit with a red

b

light.

NOTE:

 TC

 and StudScan use the same switch setting but function 

differently. StudScan detects both wood and metal studs during 

scanning, while TC

 detects only wood studs and ignores metal. You can 

distinguish between the two modes by the pale blue backlight on LCD 

in TC

 mode. StudScan is not backlit. 

MetalliWarning

 Indicator

 will 

display when metal is detected or dangerously close in TC

, StudScan, 

and

b

DeepScan

b

modes.

WIREWARNING

 DETECTION

The Zircon

®

 

WireWarning

 Detection

 continuously detects and 

alerts for live, unshielded AC (alternating current) wires in any mode. 

When live AC voltage is detected, warning indicator appears and screen 

starts flashing red until scanner is moved sufficiently away from the 

live wire. When calibration begins over an AC wire in any mode, AC icon 

will flash. 

Use extreme caution under these circumstances or 

whenever live AC wiring is present.

WARNING

Scanner may not detect AC activity if wires are 

more than 50

b

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

b

surface.

INSTALL 9-VOLT BATTERY

Always use a new 9V alkaline battery 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 scanner to 

locate items behind a surface. Use other 

information to help locate items before penetrating 

the

b

surface, including construction plans, visible points of 

entry of pipes and wiring into walls, such as in a

b

basement, 

and

b

standard stud-spacing practices.

REFINE METAL SCAN

1. 

Release Power Button, then

b

place 

scanner over one of the previous

b

marks. 

(

Figure E

)

2. 

Press and hold Power Button, 

then repeat steps 3 and 4 under 

SCAN FOR METAL. This resets metal 

calibration to a lower sensitivity and 

narrows scan area.

3. 

Repeat as needed. (

Figure F

)

NOTE:

 If any bars display,

metal is present.

SCAN FOR AC (ALTERNATING CURRENT)

Use AC Scan mode to find live, unshielded electrical wiring.

scanner will light up and a steady beep will sound.

4. 

Continue in same direction until bars reduce, then

b

reverse

b

direction. 

Mark spot where Target Indicator Bars

b

peak. The midpoint between 

the two marks is the location of the live, unshielded AC wiring. If device 

indicates live electricity over a large

b

area, reduce sensitivity of scanner to 

refine scanning area and more accurately locate the live AC wiring.

NOTE:

 AC Scan only detects live (hot) unshielded AC wiring. Refer to the 

WARNING statement under WIREWARNING

 DETECTION for important 

details and warnings about AC

b

detection.

REFINE AC SCAN

1. 

Release Power Button, then position scanner over one of the 

previous marks. This will reset to a lower sensitivity and narrow 

the scan area.

2. 

Press and hold Power Button, then repeat steps 3 and 4 under 

SCAN FOR AC.

3. 

Repeat as needed for increased accuracy.

WARNING

)

4. 

Continue sliding in same direction until bars reduce, 

then

b

reverse

b

direction. Mark spot where Target Indicator Bars peak. 

The

b

midpoint between the two marks is the location of metal object.

NOTE:

 If device indicates a large area of metal, refine scan 

to narrow area.

WORKING WITH DIFFERENT MATERIALS

Wallpaper

 Scanner functions normally on walls covered with wallpaper 

or fabric, unless the materials are metallic foil,contain

b

metallic fibers, 

or are still wet after application. Wallpaper may need to dry for several 

weeks after application.

Freshly painted walls

 It may take a week or longer to dry after 

application. If it is difficult to locate a stud in StudScan mode on dry 

or freshly-dried paint, switch to Metal Scan mode to locate the nails or 

drywall screws holding drywall to the studs.

Lath and plaster

 Due to irregularities in plaster thickness, it

b

is difficult 

for this scanner to locate studs in any stud-scanning

b

mode. Switch mode to 

Metal Scan to locate the nail heads holding wood lath to the studs. If the 

plaster has metal mesh reinforcement, the

b

scanner will be unable to detect 

studs through that material.

Highly textured walls or acoustic ceilings

 When

b

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 scanner slowly. 

This scanner cannot scan for wood studs and joists through carpet 

and padding.

NOTE:

 

Sensing depth and accuracy can vary depending on 

scanning environment conditions such as mineral

b

content, 

moisture, texture, and consistency of the wall materials.
Electrical wiring and pipes

 Depending on the proximity of electrical 

wiring or pipes to the wall surface, 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.
Studs 

Studs are normally spaced 40 cm or 60

b

cm apart on centre 

and are 38

b

mm wide. Anything closer together, or of a different width, 

may not be a

b

stud.

 STUD FINDERS WORK BY SENSING DENSITY CHANGES BEHIND THE WALL. OTHER OBJECTS CAN BE DETECTED, ESPECIALLY IF THEY ARE 

VERY CLOSE TO THE WALL. 

DO NOT ASSUME THAT EVERYTHING DETECTED IS A STUD.

- Always use a new 9V alkaline battery 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 scanner 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

b

standard stud-spacing practices.

- Always start your scan in Target Control

 (TC

) mode, which scans through standard single layer drywall up to 19

b

mm

b

deep.

- Always scan for studs at several different heights on the wall and mark the location of every target indicated by the stud finder. This

b

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

®

 wall scanners 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, 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 could contain 

these items. Use extreme caution under these circumstances or whenever live AC wiring is present.

- Studs are normally spaced 40 cm or 60 cm apart on centre, are normally 38 mm wide, and may be separated

IMPORTANT:

 

Trust but Verify

 is a technique that can help indicate “safe-to-drill” zones to minimize hitting existing metals on

b

a

b

stud, such as nails, 

screws, and protector plates. When the Crosshairs show in TC

 mode, run scanner vertically up and down

b

the stud. The stud indicators (Crosshairs, 

Edge Indicators, Target Indicator Bars, Target Spotlight, and SpotLite

 Pointer) will

b

all turn off over screws and other metal, then turn on again when the 

stud is free from metal. The "safe-to-drill" zones are typically between adjacent drywall screws, nails, or protector plates, assuming the builder properly 

installed me tal protector plates on the

b

stud, and over plumbing and electrical. If stud indicators do not disappear when running vertically up and down 

the object in TC

 mode, the absence of drywall screws, nails, and protector plates indicates this could be a non-metallic object such as plastic plumbing 

or PEX tubing, and should not be mistaken for a stud.

TROUBLESHOOTING & CONSTRUCTION TIPS

SITUATION

LIKELY CAUSE

SOLUTION

Scanner detects objects other than 

studs in StudScan mode or finds 

more objects that look like studs 

than should be there.

Electrical wiring and metal 

or plastic pipes may be near, 

or

b

touching, the back of the 

wall surface.

• Scan the area in Metal Scan to determine if metal is present.

• Check for other studs equally spaced to either side at 40

b

cm or 60 cm and 

check for the same stud at spots directly above or below the first scan area.

• Standard studs measure approximately 38 mm between edges. Anything 

smaller or larger is likely not a stud (unless near a door or

b

window).

Difficulty detecting metal.

Metal object is too deep or 

too small.

• Try calibrating in another location.

• Scan in both horizontal and vertical directions. Metal sensitivity is increased 

when metal object is parallel to the sensor (located under the Zircon

®

 logo).

Metal object reading appears wider 

than actual size.

Metal has a greater density 

than wood.

To reduce sensitivity in Metal Scan mode, recalibrate scanner over either of first 

two marks (see steps under REFINE METAL SCAN).

Studs are continuously detected 

near windows and

b

doors.

Multiple studs are in

b

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 are shielded by a 

metal conduit, braided wire, 

or

b

metallic wall covering.

Use Metal Scan mode to scan for metal, wire, or metal conduit.

Wires deeper than 50 mm 

from the surface might not 

be

b

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.

LCD screen flashes continuously 

when trying to find stud.

Scanner is experiencing 

oversaturation of exposure 

to metal.

Switch to TC

 or StudScan mode to lessen sensitivity to metal.

NOTE:

 Scanner may not beep over studs 25 mm or deeper when doing this.

Low Battery Indicator on.

Low battery.

Install a new 9V alkaline battery with an extended expiration date.

Low Battery Indicator flashes and 

scanner does not operate.

Dead battery.

Install a new 9V alkaline battery with an extended expiration date.
