The HydroScan is a towed side scan sonar system that uses simultaneous dual-frequency scanning to provide clear underwater imaging, switching freely between continuous waveform and chirp modes for enhanced anti-noise performance. An ultra narrow beam angle of 0.2° allows resolution of up to 1.25cm, making it easier to recognize smaller objects.
The complete solution includes a stainless steel towfish, waterproof topside processor and SLHydro software. Frequency options include 100, 400 and 900 kHz. HydroScan is ideal for a wide range of applications including cable and pipeline survey, mine countermeasures, dredging, archaeology, search and recovery, and more.
