The Spirent E2770 Advanced Handheld TDR Tester is one of the longest-range handheld devices of the industry—with a range of 52,000 feet.  The E2770 has precise accuracy of .05% of range for locating faults on twisted, coaxial, power, and armored cables.  From common faults such as opens and shorts to those hard-to-find intermittent faults, the E2770 finds them all with ease. It can even find faults on noisy lines.
