The Marksman II uses a two-tiered approach to ensure accurate diagnosis. The receiver converts inaudible ultrasonic sound into audible sound using heterodyne circuitry. Then, its unique Sound Signature Technology finetunes the audible sound into the natural sound emitted by the leak itself. A 5-LED signal intensity indicator and audible alarm pinpoint the exact source of the problem. An Internal Noise Control (INC) feature safeguards against ambient noise.
The Marksman II comes complete with an ultrasonic receiver, full-sized headphones, a hollow air probe, a solid contact probe and an ultrasonic emitter that helps locate faulty seals, gaskets and weatherstripping in doors, windows, ductwork and other non-pressurized enclosures. All components are packed in a sturdy carrying case.
Also available is the MDE-2000NC Marksman™ II model, which is equipped with heavy duty, noise-canceling headphones for extremely noisy environments.
