Features:
  • This professional DC 6-42V circuit tester is a must-have for automotive repair, home wiring, and industrial maintenance. It effortlessly locates circuit breakers, traces broken wires, detects current leaks, and tests continuity—all without damaging wire insulation. The perfect open & short finder for electricians, DIYers, and auto technicians to solve electrical faults in minutes.
  • Equipped with a high-sensitivity transmitter and receiver, this circuit breaker finder tool delivers crystal-clear test results via bright LED lights and distinct beeping tones. A built-in low-battery indicator (flashing red light) prevents unexpected shutdowns mid-test. Its anti-interference design eliminates background noise, ensuring you get accurate readings every time with zero guesswork.
  • Easily pinpoint open circuit breakpoints using the adjustable sensitivity feature (3 modes). Set the transmitter to the down position— a flashing green light confirms an open circuit. The receiver emits a full signal and rapid beep in normal areas; the signal weakens or vanishes exactly at the breakpoint for precise fault localization.

Our community has rated this post as helpful. If you agree, why not thank

As long as the product works as advertised this seems like a good deal for any shadetree mechanic (we're a dying breed). I checked what a similar unit would run coming from China (AE) and the price was within $1 USD. Keep in mind that price is also is before misc fees (AKA tariffs) that are added at checkout. Ordering from China also means waiting a month or so for arrival VS. day or two from Amazon.

If you are at a loss understanding the value of a device like this, I found THIS [youtube.com] excellent video of a guy explaining functionality of a similar unit.
