The Tracerline Marksman II ultrasonic diagnostic tool converts and amplifies inaudible ultrasonic sound into audible "natural" sound so service technicians can hear sounds that signify problems,

including air brake leaks, compressed air leaks, vacuum leaks and tire leaks, before they lead to major breakdowns.

The Marksman II uses a two-tiered approach to ensure accurate diagnosis. The ultrasonic receiver converts inaudible sound into audible sound using heterodyne circuitry. Then, Sound Signature Technology fine-tunes the audible sound into the natural sound emitted by the leak itself. A 5-LED signal-intensity indicator and audible alarm easily pinpoint the exact problem source.

The Marksman II is sensitive enough to detect leaks from orifices as small as 0.004 inches at 5 psi from a distance of 12 inches. An Internal Noise Control feature buffers ambient noise, allowing for use even in extremely noisy environments.

The Marksman II comes with an ultrasonic receiver, headphones, hollow air probe, solid contact probe and an ultrasonic emitter that helps locate faulty seals, gaskets and weatherstripping in passenger cabs, trailers and other non-pressurized enclosures. All components are packed in a sturdy carrying case.
