“I work on electrical issues almost every day, and this has been great for tracing opens and shorts without tearing into the whole harness. Definitely saves time in the shop.”
“Used it on a few vehicles with intermittent electrical problems and it helped narrow the fault down much faster. The tone response is easy to follow once you get used to it.”
“I’ve been wrenching for years and tools like this make electrical diagnostics a lot less frustrating. Good for tracing hidden wires and finding where the signal drops out.”

🔍 How It Works
🔍 How It Works
Connect the transmitter to the circuit or wire you want to test, then use the receiver to trace the signal along the wire path.
When the signal changes or disappears, you can quickly narrow down the location of an open circuit, short circuit, or faulty section of wire.
