Multifunction Wall Scanner
The MultiScanner
i320 OneStep
features three scanning modes:
®
™
• STUD SCAN: Locates the center and edges of wood and metal
studs up to 19 mm deep
• STUD DEEPSCAN
®
: Locates the center of wood and metal studs
up to 38 mm deep
• METAL SCAN: Detects and locates ferrous (magnetic) metal
(such as ½ in. rebar) up to 76 mm deep and non-ferrous (non-
magnetic) metal up to 38 mm deep

1. INSTALLING THE BATTERY
Press battery door release in with your finger or a coin and lift up to remove
door. Connect 9-volt battery to cable. Place into the compartment and press into
place. Replace battery door and snap shut. Battery will last approximately 2 years
under normal conditions.
2. SELECTING THE MODE
Move selector switch to the desired mode: STUD SCAN for finding wood or metal
studs; DEEPSCAN
for scanning walls over 19 mm; or METAL SCAN for locating
®
metal.
Unit will remain off if POWER BUTTON is not pressed.
6. WORKING WITH DIFFERENT MATERIALS
Wallpaper: The MultiScanner
®
i
320 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.
Freshly painted walls: May take one week or longer to dry after application.
If it is difficult to locate a stud in STUD SCAN mode on fresh paint, switch to
METAL SCAN mode to locate nails or drywall screws holding drywall to studs.
Lath & plaster: Due to irregularities in plaster thickness, it is difficult for the
i

®
320 to locate studs in STUD SCAN mode. Change to METAL
SCAN mode to locate the nail heads holding wood lath to the studs. If the
plaster has metal mesh reinforcement, MultiScanner
i
320 will be unable to
®
detect through that material.
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 in STUD DEEPSCAN
mode. If
®
irregular scanning results are received, switch to METAL SCAN mode to
locate nails or drywall screws that line up vertically where a stud or joist is
positioned.
Wood flooring, subflooring, or gypsum drywall over plywood sheathing:
Use 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.
MultiScanner
i
320 cannot scan for wood studs and joists through carpet and
®
padding. In problematic situations, try using METAL SCAN to locate nails or
screws that may line up vertically where a stud or joist is positioned.
Note: Sensing depth and accuracy can vary due to moisture, content of materials,
wall texture, and paint.

7. SCANNING IN METAL MODE
Note: When scanning for studs, use STUD SCAN mode (or Stud DEEPSCAN
Figure A
on thicker walls) to quickly locate the center and edges of wood or metal studs.
Use METAL SCAN to determine if the previous reading in STUD SCAN was a wood
stud, metal stud, or pipe. In METAL SCAN, only metal drywall screws will be found
in wood studs, while metal will be indicated everywhere on a metal stud or pipe.
METAL SCAN has interactive calibration that allows you to adjust its Sensitivity
to metal, which can be used to find the precise location of metal objects in
walls, floors, and ceilings. Maximum sensitivity is ideal for quickly finding the
approximate location of metal. However, sensitivity can be reduced by calibrating
the tool closer to metal. With reduced sensitivity, the area where metal is
indicated will be smaller. But in both cases, the metal target is in the center of
the area where the tool indicates metal is present.
1. Move mode switch to METAL SCAN mode. For maximum metal sensitivity, turn
Figure B
the tool on in the air by pressing and holding the power button. This will ensure
that it calibrates away from any metal objects. (The tool can only be calibrated
off the wall in METAL SCAN mode.)
2. (Figure A) While holding the power button, press the tool flat against The
wall and slowly slide the scanner across the surface. Mark the point where you
get the highest metal indication (the most Middle bars on the screen). If it is a
strong target, the SpotLite
steady beep will sound. Continue in the same direction until display bars reduce.
Reverse direction and mark the spot where the display bars peak from the reversed
direction. The midpoint of the two marks is the location of the center of the metal
object. If the unit indicates metal over a large area, you can refine the scanning
area to more accurately locate the metal target by following steps 3 and 4 below.
3. (Figure B) To further pinpoint the location of the metal target, scan the
Figure C
area again. Release the power button and then turn the unit back on, this time
starting on the wall over one of the previous marks. This will reset the tool to a
lower sensitivity and narrow the scan area.
4. (Figure C) To continue to reduce sensitivity and further refine the scanning
area, repeat step 3. This procedure can be repeated multiple times to narrow the
field even further.
Note: If any bars display on the screen, metal is present. Small targets or targets
deep within the surface may only illuminate some of the bars and not the center
line or audio tone. In this case, use the highest indication to determine the metal
position.
