This wire tracing kit includes a non-contact probe and a transmitter to help identify and trace wires or cables from source to termination. The transmitter injects a traceable signal into the cable, allowing easy detection of wire pairs, telephone cables, and testing for continuity and line conditions. The kit features an adjustable sensitivity for precise wire identification and false detection elimination. It comes with a probe, transmitter, two crocodile clips, and two 9V batteries. The probe measures approximately 220x50x32mm, and the transmitter is about 65x68x28mm; both units weigh around 91g.
