Abstract
A device for locating an object behind a wall lining includes a housing having a front portion fitting substantially in the palm of a user's hand. Operating switches are located in juxtaposition to the grip portion so as to be operable by the user without substantially altering grip on the housing. The device also includes a sensor including a first capacitor plate and a pair of second capacitor plates. The capacitor plates are arranged serially, and calibrated by a pulse width modulator and integrator. Operating electronics are incorporated into an application specific integrated circuit.
