Tool converts and amplifies inaudible ultrasonic sound into audible “natural” sound. Service technicians can hear sounds that signify problems such as compressed air leaks, electrical discharge, and vacuum, natural gas, propane, refrigerant, seal and gasket leaks. Marksman uses a two-tiered process to ensure accurate diagnosis. First, the receiver unit converts inaudible sound into audible sound using a process known as heterodyning. Then, the receiver fine-tunes the audible sound into the natural sound emitted by the defect itself. A 10-bar LED display indicates the intensity of incoming signals.
