Sniffer

(TEL) 27000001
Harris Tone Hunter tone probe detects audio signals on wires up to 12" away. Use an audio signal generator or build a portable audio warbler with output up to 10v peak - peak to feed signal into one end of cable pair to be checked.

Wave probe over broken out wires and the one with tone can be clearly identified. We installed brand new fresh 9v battery before shipping.

Try it once and your tool box will never be without one again. Priced at a fraction of original cost.
