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 tool 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 standard stud-spacing practices.
- Always start your scan in Target Control
up to
⁄
" (19 mm) 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 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.

stud finders 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, tool 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 16" or 24" (40 cm or 60 cm) apart on center, are normally 1
and may be separated by firestops. Anything closer together, or of a different width, may not be a stud.
IMPORTANT: Trust but Verify is a technique that can help indicate "safe-to-drill" zones to minimize
hitting existing metals on a stud, such as nails, screws, and protector plates. When the Crosshairs show
in TC
mode, run tool vertically up and down the stud. The stud indicators (Crosshairs, Edge Indicators,
™
Target Indicator Bars, Target Spotlight, and SpotLite
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 metal protector
plates on the stud, and over plumbing and electrical. If stud indicators do not disappear when running
vertically up and down the object in TC
indicates this could be a non-metallic object such as plastic plumbing or PEX tubing, and should not be
mistaken for a stud.

• Check for other studs equally spaced to either side at
16" or 24" (40 cm or 60 cm) and check for the same stud
at spots directly above or below the first scan area.
• Standard studs measure approximately 1
between edges. Anything smaller or larger is likely not a stud
(unless near a door or window).
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.
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.
Plug a lamp into the outlet and turn it on to test whether wires
are live.
Install a new 9V alkaline battery with an extended expiration date.
