This cable tracer promises to provide a tone that can reach up to 10 miles (16km) of cable and features a 9V alkaline battery. We liked that this product got great reviews from its users and promised clear and precise wire tracing. This write tracer uses special SmartToneTM technology which provides five distinct tones so you can isolate wire pairs. There is a loud speaker on the probe which ensures that the tone is easier to hear through wood, drywall and other enclosures too. There’s no need to adapters either as it comes with an angled bed-of-nails clip that allows easy access to pairs and easily connects to a telephone jack. The kit also included a nylon pouch which you can attach to your belt for easy transportation.
