An absolute lifesaver for CCTV installations. The detachable cable tester makes tracing co-ax and multi-core alarm wire through old buildings a breeze. The LED indicators are bright and clear.

I switched to this from a basic continuity pen. The 10-way switch tester functionality means I can isolate faults on 8-core telecom cables in seconds rather than messing about with a multimeter for half an hour.

Brilliant audio line finder, very strong tone that cuts through background noise on site. Dropped a star because it doesn't come with 9V batteries, so make sure you buy some before heading to the job.

I've used Tempo and Klein Tools in the past, but this black cable checker holds its own at a much better price point. The separate working mode is flawless for testing long data runs between floors.

Used this as an audio wire tracer for a complex home cinema installation. It helped me identify speaker wire pairs that the previous sparks hadn't labelled. Top quality bit of kit.

Solid build and does exactly what it says on the tin. The cable locator tester tone is quite loud, which is great on a busy site, but can be a bit deafening if you're working in a small, quiet server cupboard.

Operation Guide

How to use
  1. Preparation: Ensure the circuit you are testing is fully de-energised. Do not connect to live mains voltage.
  2. Tracing a Line: Connect the transmitter leads to the target wire. Turn the unit to 'Tone' mode to inject a signal.
  3. Locating the Cable: Use the detachable receiver (line audio finder) and sweep it along the suspected cable path. The audio tone will peak when the probe touches or is nearest to the correct wire.
  4. Continuity & Multi-Core Testing: Connect both ends of the multi-core cable to the tester. Use the 10-way switch to cycle through each core, checking the LED indicators for shorts, opens, or crosses.
