The 3M Dynatel Locator 2250M iD is designed to find the path and estimated depth of buried cables and pipes, and detect EMS MarkersThe 3M Dynatel Cable/Pipe, Fault and Marker Locator 2273M-iD incorporate advanced electronics to quickly and efficiently locate conductor or sheath (earth return) faults and trace the path of underground cables and pipes (with metallic tracer wire). It provides accurate cable/pipe, or Sonde depth measurements, giving a digital readout in inches, feet and inches, or centimeters (user-selectable). Lightweight, compact and well balanced, these cable and pipe locators allow you to accurately and easily: • Pinpoint the location and estimate the depth of all existing models of properly installed underground passive EMS markers • Read, write and conduct direct depth reading of 3M iD markers • Locate cable and pipe path • Push button depth estimation of cable/pipe or sonde • Measures signal current in the cable/pipe • Identify cable using toning • Passive locate of power cables • Pinpoints sheath or ground faults and cable breaks • Discriminates between light and heavy faults
