HOBBES 256711A Tone Generator – 1 kHz Single/Dual Tone, RJ11/RJ45/Alligator Clips, Cable Tracing & Line Identification

The Hobbes 256711A Tone Generator stands out by offering both single and dual alternating tone modes, giving technicians the flexibility to identify cables in dense bundles that single-tone units often struggle with. Its 1 kHz signal is compatible with UTP, STP, coaxial, and telephone lines, making it a versatile tool for any cabling environment. The inclusion of alligator clips alongside RJ11 and RJ45 connectors means you can trace bare wires and legacy phone lines without extra adapters.

Highlights

• Single or dual tone (alternating) for flexible cable identification
• 1 kHz tone frequency penetrates through cable bundles and walls
• Output connectors: RJ11, RJ45, and alligator clips for broad compatibility
• Overload protection safeguards the unit when connected to live circuits
• Low battery indicator prevents unexpected downtime on the job
• Compact ABS housing with included carrying pouch for portability

In daily use

Network technicians and installers will appreciate how quickly this tone generator pairs with any inductive probe (sold separately) to trace cable runs, locate breaks, or identify specific lines in a patch panel. The dual tone mode is especially useful when multiple cables are bundled together, as the alternating signal is easier to distinguish from background noise. The alligator clips allow direct connection to individual wire pairs, while the RJ11/RJ45 jacks plug straight into terminated cables. A 9V battery (6F22) powers the unit, and the low battery indicator alerts you before the signal weakens, ensuring consistent performance throughout the day.
