The Steelman 61082 wireless noise diagnostic system is built to help pinpoint squeaks rattles and other unwanted sounds in vehicles. Featuring a set of four independent wireless transmitters, the system allows technicians to monitor multiple locations at once from up to fifty feet away without running long cables. A built in speaker provides clear audio feedback, while a headphone jack offers alternative monitoring in loud environments. Visual signal strength indicators and illuminated channel buttons make it easy to identify active channels and adjust monitoring during diagnostics.
