Detector for Detecting a Current Carrying Conductor
First Claim
1. A locator for locating a concealed conductor, comprising:
- a first field detector operable to detect an alternating magnetic field along a first axis parallel to a primary axis of the locator;
a second field detector, displaced from the first field detector and operable to detect an alternating magnetic field along a second axis parallel to the primary axis of the locator; and
a processor operable to calculate a difference between a field detected by the first detector and a field detected by the second detector, and to calculate an indication of the lateral displacement of the axis of concealed conductor from the primary axis of the locator using the difference.
