Specifications

The 3M Dynatel Cable/Fault Locator is a microprocessor-based system that incorporates advanced digital signal processing techniques to quickly and efficiently locate sheath (earth return) faults and trace the path of underground cables, both copper and fiber optic (with metallic trace wire). Lightweight, compact and well balanced the cable/fault locator accurately:
 
Main Features
1)Measure and pinpoint sheath and conductor faults, locate cable path/depth quickly and easily. with this lightweight, easy-to-handle unit.
2) Four modes of operation for accurate locates, even in congested areas.
3)Precisely locates faults.
4)A simple, easy-to-use system.
