Abstract
A nailer incorporates an integrated stud finder for sensing when a stud is present. The nailer has a work contact element and a magazine for storing nails. The stud finder includes a sensor plate coupled to the work contact element of a nailer and a stud sensing circuit coupled to the sensor plate. The stud sensing circuit is provided for reading a capacitance level and for determining whether the sensor plate is positioned adjacent a stud based upon the capacitance level that is read. The stud finder also includes at least one signaling device coupled to the sensor plate for signaling to a user when a stud is present. The sensor plate is coupled to a no mar tip that is tethered to the nailer. A storage post for storing the no mar tip is positioned on the magazine for storing the no mar tip when not in use.
