FNIRSI 6-in-1 Stud Finder Wall Scanner – Center & Edge Marking for Wood, Metal, and Wires

FNIRSI 6-in-1 Stud Finder Wall Scanner

The upgraded FNIRSI stud finder introduces a newly designed positioning hole that helps you quickly mark the edges and center of objects behind walls, floors, and ceilings. Expect fast, precise readings that support careful planning before drilling or mounting.

Six detection modes for versatile projects

Exact scan mode locates the center and edges of wood and metal studs up to 0.75 in deep; Depth scan mode extends results to about 1.5 in. This makes it easier to place fasteners where you need them most.

• Wood studs: center and edges up to 0.75 in
• Metal studs and joists: center and edges up to 0.75 in
• Depth scan: center of wooden or metal members up to 1.5 in

Advanced metal and live wire detection

Non ferrous metal scan detects copper up to 3.9 in deep; Ferrous metal scan detects iron up to 4.7 in deep. AC scan finds live un shielded wires up to 2 in; copper wire scan reaches up to 1.6 in.

• Copper detection supports electrical planning
• Iron detection helps locate dense metal behind walls
• Live wire detection enhances drilling safety
• Copper wire mapping reduces guesswork during installations

Clear signals and easy calibration

The device features a digital LCD display and an audible alarm to confirm the exact object location. A rechargeable mode saves you from frequent battery changes, and automatic calibration works anywhere on the surface for quick results.

• LCD readability improves in various lighting
• Audible alerts provide instant confirmation
• Rechargeable design minimizes waste and cost
• Auto calibration enables one-step center finding

Practical versatility for many surfaces

With wide compatibility, it works on walls, floors, and ceilings, including lath, wallpaper, wood flooring, and painted or textured surfaces. This makes it suitable for shelving, mounted TVs, or picture hanging without overdrilling.

Note that results vary with wall composition. Treat the tool as a guide to locate structural elements before drilling or screwing.
