摘要： An obscured feature detector operates from a stationary position on a surface being examined. The detector includes a plurality of sensor plates positioned in an array on the underside of the device, which sense the examined surface. The sensor plates are connected to a capacitance sensing circuit, which connects to indicators positioned on the back side of the detector through additional circuitry. A handle positioned on the back of the detector allows the user to grasp the device and place it in a stationary position on the surface being examined while also observing the indicators on the back side of the detector. Increases in capacitance caused by the presence of features behind or within the surface being examined are detected by the sensor plates and the capacitance sensing circuit. The indicators identify locations of larger capacitances, associated with the presence of a feature, such as a stud, beam, or electrical wiring.
