HANMATEK Substrate Detector, Substrate Sensor, Substrate Checker, Wall Back Sensor with Depth and Distance Display, Five-in-One Upgraded Wood Precisio

Professional Stud Finder: Five scanning functions: Stud Scan Precision Mode 0.8 inches (20 mm), Stud Scan Deep Mode 1.5 inches (38 mm), AC Wire Scan 2 inches (50 mm), Ferrous Metal Scan 4.7 inches (12 cm), and Non-Ferrous Metal Scan 4 inches (10 cm). Switch to the appropriate mode as needed to help find the ends and centers of wires behind nails, screws, rebar, wooden beams, walls, floors, and ceilings. Easy to Read: The signal strength display area on the display screen clearly shows the detection depth distance to metal objects. Scan mode, detection depth, detection signal strength, battery indicator, and center point are all displayed on the screen. Fast and Accurate: The stud finder can be automatically calibrated by simply pressing the metal detection button. Note: Automatic calibration must be performed without nails, AC wires, or metal objects. Failure to do so will result in inaccurate test results. Easy to Use: The HANMATEK stud finder comes with an audible alarm (which can be turned off) and a three-color indicator light. A green light indicates no target has been found, an orange light indicates the edge of the target has been found, and a red backlight indicates the center of the stud has been found. The ergonomic design allows for a comfortable grip at any angle. The rubber backing prevents damage to walls, making it safe and convenient. [Wide Range of Applications]: The wall stud finder quickly detects hidden metal and wooden AC cables in your home's walls, floors, and ceilings, helping you avoid hazards when installing TVs, cabinets, and more.
