Working with multiple cables can be frustrating and time-consuming, especially when you're in a tight space trying to identify which wire goes where. Whether you're an electrician troubleshooting a network, a technician installing new equipment, or a DIY enthusiast working on home projects, getting the right cable identified quickly saves you time and prevents costly mistakes.

Professional Wire Tracing Made Simple

This Klein Tools probe is designed to work with the Toner-Pro Tone Generator (sold separately) to trace non-active wiring through walls, ceilings, and conduit. The responsive, durable, replaceable non-metallic conductive tip picks up the signal precisely, while the integrated LED work light illuminates your work area when you're in dark basements, attics, or utility closets where visibility is limited.

Built for Tough Professional Environments

When you're working in noisy environments like construction sites or data centers, the headphone jack allows you to use headphones (not included) to clearly hear the tracing signal without background interference. The terminal block provides confirmation that you've located the correct pair of wires, giving you confidence in your identification.
