A surface - conforming obscured feature (95) detector (10) includes a plurality of sensor plates (12, 13), each having a capacitance that varies based on the dielectric constant of the materials that compose the surrounding objects and the proximity of those objects. A sensing circuit is coupled to the sensor plates (12, 13) to measure the capacitances of the sensor plates. A controller is coupled to the sensing circuit to analyze the capacitances measured by the sensing circuit. One or a plurality of indicators (52) are coupled to the controller, and are selectively activated to identify the location of an obscured feature (95) behind a surface. |
