BEFORE YOU BEGIN
ZIRCON
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 EVERYTHING DETECTED IS A STUD.
- Always use a new 9V alkaline batteries with an extended expiration date at least 3 years beyond the current date.
Match battery direction to 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, and wiring into walls such as
in a basement, and standard stud-spacing practices.
- Always start your scan in StudScan Mode which scans through surfaces up to 19 mm deep. Scanning in DeepScan
Mode may detect an object further behind the wall that may or may not be a stud.
- 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, like a stud would.
- Readings should always be consistent and repeatable.
- Zircon stud finders are recommended for interior use only.
- Studs normally run from floor to ceiling, except above and below windows, and above doors.
- Other objects commonly contained in walls, floors, or ceilings are water pipes, 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.
- Always turn off power when working near electrical wires.
- 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.
- Studs and joists are normally spaced 40 or 60 cm apart on centre, are normally 38 mm wide, and may be separated by
firestops. Anything closer together, or of a different width, may not be a stud or joist.

LIKELY CAUSE
• Scan the area in Metal Scan Mode to determine if metal is present.
• Check for other studs equally spaced to either side at 30, 40, or 60 cm,
or check for the same stud at spots directly above or below the first scan area.
• Standard studs measure approximately 38 mm between edges.
Anything larger or smaller is likely not a stud (unless near door or window).
• The scanner may have been calibrated over a metal object,
reducing sensitivity. Try calibrating in another location.
• Scan in both horizontal and vertical directions. Metal sensitivity is increased
when metal object is parallel to sensor (located under the Zircon logo).
To reduce sensitivity in Metal Mode, recalibrate scanner over either of first two
marks (see steps under SCAN FOR METAL).
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.
Use Metal Scan Mode to scan for metal, wire, or metal conduit.
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 new a 9V alkaline battery with an extended expiration date.
