Towed side scan sonar with simultaneous dual-frequency scanning

HydroScan is a high-precision towed side scan sonar system designed for underwater imaging applications requiring excellent clarity, such as geological survey, cable and pipeline survey, and search and rescue. It utilizes simultaneous dual-frequency scanning and switches freely between continuous waveform and chirp modes, resulting in lower noise and longer range. With a beam angle of down to 0.2°, it provides the resolution required for recognition of smaller objects.

The system is available in two frequency variants - 100/400 kHz and 400/900 kHz.
