As a wire tracer or cable tracker, it follows a run from the crocodile clip leads at one end back to the receiver at the other, so you always know which cable you are looking at.\u003c\/p\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0806\/1645\/6416\/files\/download_7__result_bf8e741e-00b8-4ecc-99a8-fe713bb2dc3a.jpg?v=1790424994\" alt=\"Ethernet Cable Tester, Continuity Tester with Flashlight – image 11\"\u003e\u003cp\u003eA network tester and telephone line tester in one, it processes RJ45 and RJ11 signals side by side, and the same unit doubles as a line tracer through its crocodile clip adapters when there is no plug to connect to.
