Smart Wall Scanner - 5-in-1 Stud Sensor with LCD Display for Detecting Metal, Wood, AC Wires, Pipes and Joists

If you're hanging pictures in your home or apartment that are heavy enough to require a wall stud, the easiest way to find one is with a stud finder. Our top-pick stud sensor wall scanner can help you locate wood and metal studs faster and more accurately than tapping on the wall or guessing with a drill. Along with a tape measure and a level, it's a core part of any new homeowner's toolkit.

There are two basic types of sensors used in stud finders: electronic and magnetic. Our electronic stud finders work by detecting changes in the density of the surface being scanned. They have a visual display that pinpoints the location of the stud, and an audible signal as well. The electronic stud sensors adopt an intelligent microprocessor chip and can sense objects buried deeper inside.

This stud finder features 5 scanning modes for wood, metal, AC wiring, studs, and objects embedded up to a depth of 60mm. The basic mode scans through one layer of drywall, while the deep scan mode observes through two layers.

FAQ: Q: Can stud finders be wrong? A: This stud finder is more accurate than 95% of the ones on the market. To get the best results, we suggest continuing to scan the wall until you've located at least three studs. If the distance between each is equal, and is 16 to 24 inches, you can be confident that you've located studs, not some other building material.

Wood Mode: The stud mode can scan studs behind the wall up to 3/4 inch (19 mm) deep. The deep wall scanning mode can detect studs up to 1.25 inch (38 mm) deep.

Metal Mode: Our stud finder with metal mode relies on density changes to detect, so it cannot be judged whether wood or metal is measured. Use the Stud mode to find the subject, then adjust to the Metal mode to verify again.

AC Wires Mode: AC Wire detection indicates the presence of live, unshielded electrical wiring up to 2 inches (51 mm) deep. In all modes, this wall scanner always detects and indicates Live AC Wires.

When live AC voltage is detected, the AC warning indicator will illuminate and protect your safety.

Calibrate: Press and hold the scan button (on the side of the tool) to calibrate it. Wait until the reducing bars disappear and a short beep sounds, then calibration is complete.

Moving: Move the tool gently along the wall and keep it moving in the same direction. If you shake or lift the scanner accidentally, the device needs to be re-calibrated.

Find Stud Location: When the signal bar is full and the beep alarm is loudest, you've found the center of an object. Mark it with a pencil. Then switch to Metal Scan mode to confirm whether it is a metal. If not, it means you've found the center of a stud.

This stud finder wall scanner is accurate, fast, easy to use, and has a digital LCD display with an audio alarm. It's a great value gift for fathers, anniversaries, Christmas, or birthdays.
