Review on 🔌 POCKET TONER: Coaxial Pocket Continuity Tester Bundle for Testing and Labeling Coaxial Lines by Todd Worley

Received in the mail, unpacked and put the battery in (you need to remove the mic AND the battery cover. If you don't have a piece with a protruding spring, you haven't got it right disassembled, see diagram on box is better), attached the signaller to whoever he wanted to connect to in the house, and screwed the mic to any secret someone outside until it squeaked sharply. I marked them with a colored tape and now I can switch modems wherever I want.
