The Center Sensor Stud Finder is a highly efficient tool for locating studs in walls. Unlike traditional stud sensors that only locate the edge of the stud, our innovative product uses center find technology to accurately pinpoint the center of the stud, even when held at an angle. This feature ensures a more precise read and saves time during use. In addition to stud detection, this stud finder also has AC and live wire detection capabilities, providing added safety during your projects. The audible alert and directional LED arrows clearly notify you once the stud is located, making it easy to mark the center of the stud with the center marking channel. With a detection depth of 1-1/2 inches for both wood and metal, this stud finder is suitable for a variety of applications. Its constant auto-calibration feature ensures accurate readings every time, further enhancing its efficiency. The slim profile of this stud finder makes it easy to handle and store, while the directional LED arrows provide visual guidance to the stud location. AAA batteries are included, so you can start using this tool right away. For more information on this product and to explore other Dewalt tools, click here.
