The Multi-Purpose Stud Finder cannot be used as a depth gauge. The
detector will not detect water or gas pipes shielded by metal materials; it may
detect them in the same manner as metal only.
The detector is not suitable for use on objects insulated with foil
Sensing depth and edge detection can vary due to moisture content of
materials, wall texture and paint, etc.
Push the clip at the bottom of the battery door to open.
Insert a 9v battery (not included) matching the positive (+) and negative (-)
terminals to the battery.
Snap the battery into place and replace the door.
Low Battery Indicator: The Low Battery Indicator icon displays when the
battery level is getting low and there is insufficient battery power to
operate the tool properly. Please replace the 9-volt battery with a brand-
new battery immediately
GENERAL SCANNING
For optimum scanning results, it is important to properly hold the MULTI
PURPOSE STUD FINDER and move slowly when scanning. The following
tips will provide more accurate scanning results:
6. Grasp the handle with your thumb on one side and your fingers on the
other side. Ensure fingertips are resting on the handle and not touching
the surface being scanned or the scanning head of the tool
7. Hold the tool straight up and down, parallel to the studs, and do not rotate
the tool.
8. Keep tool flat against the wall and do not rock, tilt, or press hard when
slowly sliding across the surface being scanned.
9. 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.
10. If you are 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 has not 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.
11. 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
12. To avoid surprises, remember that studs or joists are normally spaced 16 or
24 in. (41 or 61 cm) apart and are 1 1/2 in. (38 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.
SCANNING DIFFERENT SURFACES
1. Wallpaper: MULTI PURPOSE STUD FINDER 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.
2. Freshly painted walls: May take one week or longer to dry after application
3. Lath & plaster: Due to irregularities in plaster thickness, it is difficult for the
MULTI PURPOSE STUD FINDER to locate studs in Stud modes. Change to
Metal Scan mode to locate the nail heads holding wood lath to the studs. If
the plaster has metal mesh reinforcement the MULTI PURPOSE STUD
FINDER may be unable to detect through that material.
4. 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 1 1/2 in. scan 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.
5. Wood flooring, subflooring, or gypsum drywall over plywood sheathing: Use
Stud 1 1/2 in. scan mode and move the tool slowly. The Signal Strength
Indicator may only display limited bars when the tool locates a stud through
thick surfaces the MULTI PURPOSE STUD FINDER cannot scan for wood
studs and joists through concrete or 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.
