Ideal for thick walls and complex wall conditions, manual calibration corrects detection data for higher accuracy, adapting to various complex home scenarios
3. LCD Display & Clear Audio Reminder Comes with a high-definition LCD display to clearly show target status, stud edge/center indicators and battery level for intuitive viewing. A constant beep alert will sound when locating stud centers, dense metal objects or live AC wires, allowing you to quickly confirm hidden wall structures with both visual and audio prompts
4. 5-in-1 Practical Detection Modes Features 3 adjustable stud scan modes (0.5/1/1.5 inch) for locating wooden and metal studs, as well as independent metal scan and AC wire scan modes to meet daily household installation and renovation needs. Metal pipes can be incidentally detected under metal mode, with no dedicated pipe positioning function
5. Scientific Safety Warning & Wide Compatibility The AC live wire warning function runs continuously in 3 stud modes and metal mode to alert you to hidden live wires in advance. It is compatible with most common wall surfaces, including drywall, painted walls and wallpaper walls. For plaster walls, textured ceilings and special materials, adjust scan modes or use auxiliary padding as instructed to optimize detection accuracy
