Wall detector, four-in-one detection mode, multi-functional precise positioning

1. Wide application: This stud detector can help you find the center position of wooden studs in wooden boards and drywall walls, as well as the positions of metals and AC wires. In this way, you can accurately install TVs and cabinets, drill holes in the wall, etc. 2. Four - in - one detection mode: This stud detector has 4 different modes to switch: stud scanning, depth mode, metal scanning, and AC scanning. 3. Multifunctional: Stud scanning is used to locate the center and edges of wooden and metal studs at a depth of 19 mm; the maximum depth scanning locates at a depth of 38 mm; the maximum metal detection depth is 60 mm; AC scanning can detect AC wires at a depth of 51 mm. 4. Screen display and alarm information: During the detection process, the screen displays the detection mode, signal strength, direction reference, etc. In addition, the intensity of the beep depends on the distance between you and the target. You can use the marker to mark the position where the sound is the loudest. It also has an AC warning function. 5. Easy calibration: The detector needs to be calibrated before each scan. First, select the mode, then hold down the scan button (located on the right side of the tool) for calibration. When the weak indicator bar disappears and a beep sounds, the calibration is completed. In the metal/AC mode, you need to hold the device in the air for calibration.
