Craftsman sensor and level set locates framing studs and lets you check easily if there is any inconsistency in your walls. The stud finder detects wood and metal studs up to 3/4-in deep and identifies their center for accurate results. Moreover, it detects the presence of live AC for more safety. It features auto-calibration for consistently accurate readings. The level comes with 3 angle vials: 90°, 180° and 45°. Over-moulded rubber endcaps protect surfaces from potential damages and provide shock resistance. Integrated hang holes are designed for easy storage, while the magnetic backing allows hands-free operation on steel surfaces.
