The Klein Tools VDV500-123 Probe-PRO Tracing Probe traces non-active wiring in Ethernet, telephone, speaker, coax, and data cable systems when used with a compatible tone generator such as the VDV500-063 Toner-PRO. It features a worklight for use in dark spaces, a stay-on power button, adjustable volume, and a durable replaceable non-metallic conductive tip. A headphone jack supports use in noisy environments. Runs up to 25 hours on 4 AAA batteries. Backed by a 1-year limited warranty.
Can the VDV500-123 be used with tone generators from other brands?
The VDV500-123 probe is broadband and picks up tones across the standard frequency range used by Klein Tools generators as well as many third-party toners. It pairs optimally with the VDV500-063 or VDV500-163 Klein generators.
What does 'non-metallic conductive tip' mean for field use?
The probe tip conducts tone-pickup signals without scratching or cutting cable insulation. The non-metallic material also reduces the risk of accidental short circuits when probing near terminations. Tips are field-replaceable — Klein sells spare tips separately.
How do I locate a specific cable in a tightly packed bundle?
Sweep the probe tip slowly along the bundle approximately 1 cm from the cables. Audible tone intensity increases as the probe nears the toned cable and fades as it moves away. For cables in conduit, press the probe tip firmly against the outer conduit surface.
What battery does the VDV500-123 require?
4 x AAA — the same format as the VDV500-063 generator, simplifying battery management when both are carried together in the field.
Should I buy the VDV500-123 separately or buy the VDV500-820 set?
If you already own the VDV500-063 generator, the VDV500-123 fills the kit without duplication. Starting from scratch, the VDV500-820 set (VDV500-063 + VDV500-123 bundled) delivers both at a lower combined cost.
