Without a tracer vs. with the circuit finder.

Questions, answered plainly.

It's for 6–42 V DC systems – most cars, motorcycles, vans and many trucks. Never use it on high-voltage EV or hybrid circuits.

Yes, it's a tracing tool and doesn't replace a multimeter for measuring voltage or resistance.

The receiver can pick up the signal through trim and insulation, which helps you narrow down where to look before removing anything.

Check the product listing and manual for battery type and whether batteries are included.
