The Major Tech MTC30 is a professional cable mapper built for voice, data, and video testing. It works with phone (RJ11/RJ12), network (RJ45), and coaxial (F-Connector) cables, making it a versatile tool for telecom, networking, and AV installations. In one step, it maps out cable connections and detects faults like split pairs, shorts, opens, and miswires. A large backlit LCD provides a clear layout of the wiring, helping with quick diagnostics.

This tester also features a built-in tone generator for easy cable tracing, especially when paired with the optional MTC40 tone probe. It supports both shielded and unshielded cables up to 305 meters, with a detachable remote terminator for testing long runs. The pass/fail function gives instant verification of correct wiring. Powered by batteries and designed for portability, it's an essential tool for electricians and network professionals.
