What is included in the VDV500-820?
The VDV500-820 bundles the VDV500-063 Toner-PRO (5-cadence analog generator) and VDV500-123 Probe-PRO (replaceable-tip tracing probe), plus 8 x AAA batteries (4 for the generator, 4 for the probe) and a carrying pouch.
Why choose the VDV500-820 over the VDV500-920?
The VDV500-820 is pure analog with 5 distinct cadences — maximum simultaneous-trace flexibility for multi-technician jobs. The VDV500-920 offers 3 cadences but adds digital toning, which filters EMI better in dense cable environments. Choose -820 for high-cadence analog tracing; choose -920 when digital mode filtering is valuable.
Can the components be used with other Klein tone-probe equipment?
Yes — the VDV500-063 generator and VDV500-123 probe are also sold individually and interoperate with the VDV500-163/VDV500-223 digital series as well as compatible third-party equipment.
How does the set handle multiple technicians tracing simultaneously?
Each technician selects a different cadence on the VDV500-063. Five distinct cadences allow up to five simultaneous trace operations on different runs without confusion between workers listening for different tones.
Can the VDV500-820 trace coaxial cable?
Yes — coaxial cable is included in the supported cable types alongside Ethernet, telephone, speaker, video, and other data cables. Connect via alligator clips or the appropriate RJ connector at the termination point.
