DIGITRACE 50 is a coiled 4.5mm (0.18”) diameter fiberglass rod on a reel, which incorporates a copper wire. The wire is connected to a DIGITEX Signal Generator to pass a 33 or 8 kHz traceable signal either through the entire length of the rod or just the end. Use this in tracing non-metallic pipes, such as drains or sewers, plastic pipes, plastic ducting, etc. The length is 50 m (164 feet).
