5-in-1 Wall Stud, Metal & Live Wire Detector

5-in-1 Wall Scanner for Studs, Metal, Wires and Thickness

- This electronic wall detector combines stud finding, metal detection, live wire warning, and wall thickness gauging in one compact handheld tool. Designed for drywall and wood board applications, it helps you locate hidden studs, pipes, rebars, and AC cables before you drill, cut, or mount fixtures.

The detector offers multiple stud modes that locate both the edge and center of wooden studs at different depths: up to approx. 1/2 inch (13 mm), 1 inch (25 mm), and 1 1/2 inches (38 mm) wall thickness. In metal mode, it identifies common metals such as iron, lead, and aluminum behind surfaces up to about 2.36 inches (60 mm). A dedicated live AC wire mode detects energized cables up to around 2 inches (51 mm) behind the wall, helping you avoid electrical hazards. All detection modes feature automatic calibration to improve accuracy and an AC warning function that alerts you when live voltage is present, even in non-wire modes.

The illuminated LCD backlit display clearly shows the selected mode, signal strength, and target position, while audible beeps guide you as you move across the surface. A smart beep feature increases in intensity as you approach the stud or metal center point. The ergonomic, anti-slip body is designed for one-handed use, making it suitable for both professional tradespeople and home users. A low-voltage indicator reminds you when the 6F22 9V battery (not included) needs replacing. Operating temperature range is 0°C-40°C, allowing dependable use in typical indoor jobsite and home conditions.

Why It's a Smart Choice
