The Platinum Tools TP250C tone tracer is an ergonomic, high-sensitivity probe for field service professionals. Used in conjunction with any analog tone generator, the ToneSeeker identifies wire and cable without having to make direct metallic contact with the conductor. Compatible with any analog tone generator, the ToneSeeker emits a clear and loud tone as a cable is traced. Frequency filtering blocks out background noise and the auto-off extends battery life. The surface area and shape of the replaceable tip is optimized to detect weak tones and to penetrate wire bundles to make wire tracing easy.
