Claim 18:
19. An apparatus for detecting obscured features and obscured electrical wires behind a surface, the apparatus comprising:
an obscured feature sensing element to sense an obscured feature;
obscured feature sensing circuitry operatively coupled to the obscured feature sensing element, the obscured feature sensing circuitry configured to measure a sensor reading on the obscured feature sensing element;
an obscured feature indicator to display to a user that an obscured feature has been detected behind a surface, based on the sensor reading;
a live wire sensing element to detect an obscured live electrical wire;
electrical wire sensing circuitry operatively coupled to the live wire sensing element, the electrical wire sensing circuitry to receive signals originating from the live wire sensing element; and
a live wire indicator to display to the user a variable electrical field strength of a detected live electrical wire, based on the signals originating from the live wire sensing element,
wherein the obscured feature indicator and the live wire indicator are concurrently displayed to the user, wherein the live wire sensing element is decoupled from the electrical wire sensing circuitry before the obscured feature sensing circuitry is operatively coupled to the obscured feature sensing element.
