A method and apparatus for detecting a discontinuity in the wall of a ferrous object is disclosed, which utilize a bank of sensors where each sensor is configured to detect a difference in magnetic flux across a predefined area. Sets of readings from the sensors are converted to images, from which the existence and location of a discontinuity can be detected.
