5 Best Tone and Probe Tracing Kits of 2022 – Consumer Reports

A tone and probe tracing kit is a tool that allows professional technicians or cable installers to identify a wire within a bundle, at a cross connect or at a remote end. There are two parts to this tool: the generator tone which injects a signal onto the cable to be traced and the tracing probe which is used to trace out the wire. The tone and probe tracing kit provides the ability to check-Voltage on wire pairs as well as generate a tagging tone along the wire, which is then picked up by the tracing probe.

A tone and probe kit is an essential electrical tool that no technician or installer can do without. Consumers use this kit to identify wires from a bundle, to monitor voltage passing through the circuit, to check breaks in the circuit and to trace wires through walls.

There are numerous models and designs of tone and tracing kits in the market, each having different features making it a slightly difficult task to determine which model or design to buy. Therefore, we have reviewed many of these kits and selected 5 best tone and probe tracing kits of 2022.

It uses the IntelliTone technology to detect digital signals, rejecting noise and false signals, to locate and trace data cabling on active network. It also locates 500 to 1200 Hz Analog signals on inactive networks.

There are eight multiple-level LEDs that light successively as the signal strength increases for prompt isolation of a single cable within a bundle. This simplifies signal interpretation in noisy environment making it very easy and fast to locate cables, thereby saving time.

The Pro Toners produces four different Analog songs which alternate every time the pair under test is shorted.

The IntelliTone Pro 200 Probe features a Cablemap capability that identifies common cable that are wired wrongly in twisted pair cabling, eliminating the need for a Wiremap. The Cablemap function helps to validate RJ11 and RJ45 connectors by testing continuity and discovering short circuits, open circuits and crossed-pair wiring faults on all four pairs of UTP and STP twisted pair cabling.


  • Eliminates confusion over cable location
  • Simplifies signal interpretation in noisy environments with the multiple-level LED indicator
  • Isolates a cable that is within the bundle using a signal with minimum radiation
  • Fast and easy to locate cables saving hours of cable location projects every week
  • Simple and easy to operate knobs
