Review on 🔊 Jonard PT-350 Replacement Speaker: Enhance Your PT-300 Pocket Continuity Tester and Toner by Jay Elgouhari

Excellent product. Used to check for a bad cable connection from my RV to the TV. Very easy to use with good instructions. All of the RV cords were behind the walls, but with this device I was able to locate the faulty T-connector in minutes. I like that it fits in your pocket, beeps loudly and flashes to indicate a good connection. This device is indispensable when long cables are to be shot behind walls.
