Kongsberg 1171 Clariscan Imaging Sonar

Kongsberg Discovery’s innovation in domed-sonar technology combines a wide-bandwidth composite transducer with a patented acoustic lens to provide unprecedented image clarity from a domed sonar head. The result is Clariscan - a high-performance, multi-frequency imaging sonar.
