Three detection modes for versatile use: metal, live AC cable, and wood stud detection. Easily switch modes to suit the task and wall type, making the NF-513 wall detector a reliable tool for professionals and DIY projects alike. Deep scanning capability: metal detection depth up to 80 mm (magnetic and non-magnetic metals), live AC cables up to 50 mm, and wood studs up to 38 mm. The broad detection range matches standard drilling needs and reduces the risk of hidden obstacles. Adjustable sensitivity settings: real-time sensitivity control to optimize accuracy. Lower sensitivity improves precision in complex environments; higher sensitivity enlarges the detection range. This helps the device adapt to different wall materials and construction types. Intuitive color display: 2.4-inch high-definition color screen with 240 x 320 resolution clearly shows detected objects with highlighted information. The bright display remains readable in low light, and true voice guidance provides additional wire-detection cues. Applications: - Mount a TV, shelf, or artwork by locating studs for secure anchoring. - Install outlets or run cables while avoiding live wires and metal obstructions. - Renovation projects that require identifying pipes or conduits behind walls.
