• Calibrate and Scan — Press and hold the metal detection button to calibrate. Wait for the device to indicate calibration is complete (usually a beep or light change). Then, slowly slide the device horizontally or vertically across the wall surface.
• Interpret Readings — Observe the HD LCD display for signal strength, depth, and center point. A green light means no target detected. Orange indicates the edge of a stud or object. Red light and an audible alarm signal the center, indicating where to drill.
• Identify and Mark — Once the center is detected, mark the spot with the updated positioning hole. Use the multiple scanning modes (stud, AC wire, metal) to confirm what you are detecting before proceeding with any installation or drilling.
