LCD Digital Wall Scanner

This digital wall scanner features a backlit LCD interface that responds to object proximity with a climbing progress bar and incrementing percentage; at maximum detection strength, the display fills completely and activates a continuous buzzer. Its ABS housing ensures durability during regular handling, and it operates using a built-in 9V 6F22 battery (supplied), powering down after approximately 150 seconds of idle time. Certified for stable performance between 0–50°C and 35–55% RH, it tolerates broader storage conditions (−10 to 60°C). Three scanning modes—Stud Scan, Metal Scan, and AC Scan—are selected manually, each adjusting detection parameters and LCD visuals accordingly. In Stud Scan mode, directional arrows indicate position, and depth presets (Deep/Middle/Exact) support applications from shallow trim fixing to deep structural locating (up to 38 mm). Metal Scan locates steel components including rebar and pipes up to 60 mm deep, while AC Scan detects live wires up to 51 mm deep—both include sensitivity reduction options for high-signal scenarios. A magnetic tip collects nails, and the removable bubble level facilitates precise horizontal alignment.
