This fault tester has a pretty long distance measurement range of 2.4 miles on auto. The screen is very clear and bright. You can tell someone designed this to be seen easily outdoors during the daytime. Once you understand the functions of the machine, it is easy to navigate. I would have liked to have seen a little longer battery time so that you have a little extra buffer between days, but for the type of device it is, 10 hours is quite a bit. I like the fact that it’s a multi-function cable fault tester as well, making it a more versatile device. Overall, it gives a lot of data, in order to diagnosis the fault problems and is worth the investment. Review: It's doing something - This fault locator may be smarter than I am, because I haven't quite figured out how to use it properly. I hook it up, plug the alligator clamps on, and it reads a bunch of things at me, but I can't make sense of them because I am not an electrician as a profession. I am a DIY hobbyist who likes to tinker and fix things by myself when at home, but this is a bit too advanced for me at the moment. I know it is functional, but I am the one who is faulty since I am not skilled enough to use it to its potential. A professional electrician would definitely find this useful. That's not to say that this is without flaws, as the lack of proper instructions and tutorials makes this a sub-par offering since it is not beginner friendly. ## Features - 【Multi-Function OTDR Fiber Tester】 GOYOJO optical fiber tester combines OTDR, optical power meter (OPM), stabilized light source, visual fault locator (VFL), RJ45 sequence testing and cable tracking in one compact tool.
