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

The Jonard PT-300 coax continuity tester arrived quickly and was exactly as described. It's packed with a battery, so I was immediately ready to test a few coax lines around the house to confirm which line goes to which room and when. It's very easy to use and the sound was loud enough to be heard without being too loud. The price was reasonable and the quality seems very high.
