The mechanical listening stick uses mechanical amplification for detecting and pinpointing leakage. It has an acoustic resonant chamber for noise amplification. It is ideal for individuals that have difficulty in differentiating between static and leak noise on an electronic listening stick.
The VM Aqua-Trace Electronic Sound Tracing System combines the advantages of an electronic listening stick with a ground microphone and an acoustic dome listening sensor. The latest audio system technology has been used to design a high quality electronic sound tracing system. The system provides automatic frequency dependant volume control to boost the lower frequencies, as well as a manual control to accommodate individual hearing abilities.
