A professional-grade analog tone generator for tracing open-ended, non-active wiring, pairing with the Probe-Pro tracing probe (sold separately) to find and identify individual conductors.
- Connects via: angled bed-of-nails clips or an RJ11 plug into telephone or RJ45 data jacks
- Five distinct tone cadences for telling wires apart
- Tests continuity and polarity, shown on labeled LEDs
- Auto power-off and low battery indicator; runs on 4 AAA batteries (included)
Best for: voice/data/video techs tracing and identifying conductors in wiring that isn't energized. Do not use on energized circuits.
