HQ400 Multibeam Echosounder

The HQ-400 Multibeam Sonar System offers integrated functionality for seamless underwater terrain measurement.

• Integrated Design: Combines small multi-beam sonar, temperature sensor, attitude, positioning, compass, and other core sensors into a compact and integrated system.
• Calibration-Free Operation: With no installation and calibration required, the HQ-400 Multibeam Sonar System offers convenience and ease of use, especially on small unmanned carrier platforms such as the Apache 3 and Apache 6.
