Mechanical Scanning Sonar 700kHz 

Underwater Acoustic Camera 360° Omnidirectional Imaging Sonar

The MiniUAC-700M mechanically scanned sonar is mainly used for detecting underwater targets. It can acquire target information within a 360° field of view and display data in real time for target recognition and other applications.


This sonar model is specially designed to be mounted on Unmanned Surface Vehicles (USVs), underwater robots (ROVs, AUVs, UUVs) and various other embedded carriers. It is applicable to underwater engineering inspection, emergency search & rescue, salvage and other fields.


It adopts fully domestic hardware and software, and is compatible with Tritech sonar display & control software. In addition, an SDK package is available for deep integration scenarios to support user secondary development.
