Main highlights

• •▲WIRE TRACING MULTIFUNCTION - Fast to locate the breakpoint without wire's cover damage, Find wire on all types of connected operating Ethernet switch /Router/PC terminal. Perfect for tracking RJ11, RJ45, cables or other metal wire (via adapter)；And also with the Battery（10V-110V） positive and negative measurements function.(Note: The receiver only has RJ45 connection port, not RJ11 connection port. )
• •▲WIRE TRACKER - The Line Finder can trace not only Ethernet LAN wires, but also electrical and speaker wires when connecting to the alligator clip; In this situation, the wires must be in power-off status, otherwise the units will be damaged; It is recommended to stripe down some of the wires when connecting through the clip; Select "SCAN"; Emitter works properly if the "SCAN" indicator is on; Use the receiver to find target wires.
• •▲NETWORK & TELEPHONE LINE TEST - The Line Finder testes physical connection status of network cable, such as open circuit, short connection, miswire and reverse connection; Use the emitter to test the status of working of telephone lines (such as judging TIP or RING line), test the line level, positive and negative polarity detection; Adjust the volume of receiver by pressing the volume rotary knob.
• •▲EARPHONES DESIGN - With a pair of Earphone, you can just connect the earphone to the headset jack of receive to get clear information in a noise environment, Adjust the volume knob to make the volume proper and avoid being interfered. Notice that if the sound is low, you should check whether the battery is powered off or not, and the LED flashlight allows operation in dark situation.
• •▲Lifetime After-Sales Service and You Will Get: 1x Emitter with double RJ11 RJ45 interface, 1x Receiver with BNC interface,1x Pair of Earphone ,1x RJ11 Clip Adapter Cable,1x RJ45 Cable,1x Storage Box,1x English User Manual , Battery Not Included.

Main highlights
