HQ-400 Integrated Compact Multibeam

Model:HQ-400

HQ-400 Integrated Compact Multibeam Sonar: Combines sonar, temperature sensors, attitude sensors, positioning systems, and compasses into a single unit. Its all-in-one design eliminates the need for installation calibration. The compact form factor enables easy mounting on small unmanned platforms, making it ideal for underwater terrain mapping in rivers, lakes, cross-section surveys, reservoir volume assessments, and channel scanning.
