Fluke Networks 26000900 Tone generator

The Pro3000 Analog Tone and Probe is ideal for cable tone testing and tracing in inactive networks, especially for identifying individual pairs with SmartTone technology. Angled banana plugs and insulated alligator clips make it easy to access individual wires, and the RJ11 connector is perfect for use with phone jacks. Thanks to the powerful speaker of the network probe, you can hear signals through drywall, wood, or other coverings, allowing you to quickly and easily locate lines. You can transmit this loud tone up to 10 miles (16 km) on most cables. The device's nylon pouch conveniently fits onto your belt, ensuring you are well-equipped for any wire labeling task.
