Automatic calibration adapts to different wall materials, and the low battery indicator ensures you're never caught off guard. Built with durable ABS plastic and an ergonomic grip, it's a reliable companion for any DIY or professional project.

Ideal use cases

• Avoiding live AC wires when installing electrical fixtures
• DIY home improvement projects and professional carpentry work
• Checking wall composition before hanging heavy items

Good to know

The stud finder automatically calibrates when placed on the wall; hold it still until calibration completes. For best results, scan slowly and keep the unit flat against the surface. The backlight turns on automatically in low light, and the unit powers off after a period of inactivity to conserve battery. The 9V battery is included, so you can start using it immediately. Store in a dry place within the recommended temperature range to maintain accuracy.
