Buried utilities represent a major challenge to electricians who need to trace and trouble shoot such systems. They also represent a hazard to excavation crews. Improperly performed digging can cause cable or pipe damage resulting in personal injury, costly repairs and penalties. Using superior design and powerful software, NNDT offers several new performance features, establishing them as the new standard for locating and pinpointing faults in the underground systems. Distance sensitive Left/Right indication guides the user to the exact location of the buried utilities which saves time and effort not available on standard locators. The Signal Select and Distortion Alert provide superior accuracy by visually indicating a clean signal of the traced line. versus "ghost and 'return' path of false signals coming from the neighboring lines, and keeping the user on the target line.
