Thanks to my knowledge gained in practice I can confidently recommend this Industrial and Scientific cable tester to fellow professionals. The tracker works seamlessly, reliably tracing cables without any glitches. It detects cable faults quickly, and the LED light indicators make it easy to identify where the issues are .The only con would be its bulky design, but the ease of use and accuracy more than compensate for it. Overall, an amazingly handy tool for anyone dealing with network and cable tests..
