The UW-350 hydrosounder is a testament to Data Physics’ commitment to innovation and excellence in underwater acoustics. This easily transportable device packs a powerful punch, providing a versatile operating bandwidth ranging from 20 Hz to 20 kHz. What sets it apart is its ability to maintain excellent beam patterns up to 1 kHz, making it a valuable tool for a wide range of underwater applications. 

One of the standout features of the UW-350 is its impressive average sound pressure level across the operating band, measuring at 165 dB re 1 µPa at 1 m. This level of performance ensures that the hydrosounder can effectively transmit acoustic signals in challenging underwater environments. But that’s not all; the UW-350’s capabilities allow for an operating depth of 188 meters – which can be extended – allowing for deployment on the hull of deep-diving naval submarines. It’s no surprise that the UW-350 is trusted and employed by the navies of numerous countries around the world. 

Segmented Ring Transducers Provide Unmatched Performance
