The Klein Tools ESF050 is a professional-grade stud finder that locates wood and metal studs up to 3/4-inch deep behind drywall in a single continuous pass.

The device features intuitive LED indicators, mutable audible alerts, protective wall pads, and ergonomic finger guards to safeguard finished surfaces while you work. Designed for both commercial contractors and homeowners, this compact scanner delivers reliable, repeatable results in any environment with instant auto-calibration, hands-free one-touch operation, and operating temperatures from 32°F to 122°F. Powered by two included AAA batteries.
