Snap Shot Advanced TDR and Fault Finder

SnapShot Advanced TDR Cable Fault Finder

Accurately finds cable length, locates impediments in the cable and conditions at the end of every wire in your data, power, communications or video system up to 3,000 ft.

With the complexity of today's electrical, data, voice and video signal carrying systems, you need a fault finder time domain reflectometer (TDR) tool that is fast, accurate and easy to use to see down the wire and show the exact conditions that exist. Snap Shot™ is that tool.

Made in the USA with Advanced Spread Spectrum TDR technology, Snap Shot™ is the new 21st century tool for cable fault location for every type of cable in any industry. Advanced Spread Spectrum TDR technology works in all wire environments and is immune to voltage, current, or data stream disruptions. See the true picture of your wiring and cable systems with the Snap Shot™ cable fault detector and length measurement tool today.
