FNIRSI 6-in-1 Stud Finder Wall Scanner – Center & Edge Marking, Live Wire & Metal Detection

Meet the FNIRSI 6-in-1 Stud Finder Wall Scanner

Designed to help you locate hidden supports, wires, and metal behind walls, this tool blends speed with accuracy thanks to a newly designed positioning hole. It makes it easier to mark the edges and center of targets in one simple motion, supporting mounting tasks, renovations, and décor projects with less guesswork.

6 in 1 detection gives you a versatile toolkit in a compact device. In center and edge mode, it pinpoints the center and edges of wood and metal studs up to 0.75 inches deep; in depth scan mode, it locates centers and edges up to 1.5 inches deep. It also detects non-ferrous metal such as copper up to 3.9 inches and ferrous metal such as iron up to 4.7 inches, helping you plan around potential obstacles before drilling. The AC live wire scan reveals energized lines up to 2 inches deep, while copper wire detection reaches up to 1.6 inches.

The device features a digital LCD display and an audible alert, providing clear feedback as you scan. A rechargeable mode reduces the need for frequent battery changes, while auto calibration lets you start scanning anywhere on the wall and get a reliable center read in a single step, speeding up your project without sacrificing accuracy.

Practical design choices extend the usefulness across real-world surfaces: lath, wallpaper, wood flooring, acoustic ceilings, and painted walls are all compatible with the detector. Lightweight yet capable, this tool supports DIY installations, home improvements, and light construction tasks with a straightforward, non-intimidating workflow.
