Features

    Multifunction Cable Tracing:The Mastfuyi wire tracer can quickly identify and trace target cables within a bundle without damaging the insulation—especially suitable for locating RJ11 and RJ45 cables. With the included alligator clip adapter,circuit tracer can also trace other metal cables, such as power lines and speaker wires. Note: Always disconnect the power before tracing metal cables to avoid damaging the device
  • Fast & Accurate Network Cable Sequence Testing:The network tester supports POE live cable tracing, with 60V voltage resistance to prevent burning, and can directly calibrate cable sequences. It uses digital signal technology to solve the problem of shielded cable identification (the G key is the shielded cable test light). It can quickly locate the required cables under carpets, inside decorative walls, on ceilings, and in other cable bundles
  • Line Fault Detection: Use the transmitter and receiver for pin-by-pin mapping to verify the physical condition of network cables.Wire break locator can detect open circuits, short circuits, wiring errors, and reversed polarity. LED indicators clearly show the wiring sequence and support long-distance testing up to 30 meters
  • Telephone Line Testing and Continuity Detection: Independently test the status of telephone lines—using only the transmitter, you can detect idle/ringing/busy status and determine TIP (microphone side) or RING (ring side). Cable tracer also features continuity testing to check cable integrity, line levels, and polarity, providing accurate diagnostics for telecommunications and low-voltage applications
  • Wide Application: This multifunction broken wire detector tool is suitable for telecommunications engineers, network technicians, and IT professionals for troubleshooting and maintaining structured cabling systems
