Spectronics Corporation has introduced the Spectroline® Marksman™ ultrasonic diagnostic tool, a highly accurate instrument that converts and amplifies inaudible ultrasonic sound into audible “natural” sound. 
Now service technicians can easily hear sounds that signify problems such as compressed air leaks, electrical discharge, as well as vacuum, natural gas, propane, refrigerant, seal, and gasket leaks. This allows technicians to repair them long before they become major headaches. The 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’s Sound Signal Technology™ 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.
