<p>An implementation of an apparatus and method for sensing electrical wiring, for example, hidden behind a surface such as a wall is provided. The apparatus and method use multiple sensor signals, which may measure electric fields or changes in a dielectric. Pairs of signals are combined and compared to a sensed reference signal. Multiple sensors help in determining a direction or gradient to electrical wiring. Combining or averaging sensed signal before comparing the combined signal to a reference signal helps to make the detection of electrical wiring less dependent on the relative orientation between the sensor and the electrical wiring.</p>
