Electricians and IT folks, this 200EP Wire Tracer Kit is a lifesaver for tracking down cables and diagnosing issues! It includes a tone generator (transmitter) and a probe (receiver) to help you identify specific wires in a bundle, trace lines behind walls, or find shorts and breaks. Works on telephone, network (CAT5/6), security, audio, and other low-voltage cables. The detector gives both audible tones and visual LED indications, making it easy to pinpoint the right wire even in crowded panels. It has a high-gain amplifier for sensitive detection and comes with different probe tips for various applications. Made from tough ABS plastic and comes with a handy storage bag. Requires a 9V battery (not included). A must-have tool for anyone doing cabling installations, repairs, or troubleshooting. Saves time and frustration on the job!
