StudSensor Pro SL-AC can scan effectively through most sheet materials, including:
• Bare wood flooring (in DeepScan mode)
• Linoleum on wood base
• Gypsum drywall over plywood sheathing
• Wallpapered walls (if dry)
• Textured ceilings if uniform thickness (Place a thin piece of cardboard on ceiling
and scan through it to avoid damage
to texturing.)
The Zircon StudSensor™ Pro SL-AC
detects wood and metal studs
and joists in walls, floors, and
ceilings. It features two scanning
modes, recessed LEDs, a durable
high-impact case, and the

INSTALLING THE BATTERY
This equipment has been tested and found to comply with the limits for a Class B digital device, pur-
suant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the
equipment is operated in a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no guar-

To avoid surprises, remember that studs or joists are
normally spaced 16 in. (406 mm) or 24 in. (610 mm)
apart and are 11⁄2 in. (38 mm) in width. Anything
closer together or a different width may not be a
