About the HN-400M

The CHCNAV HN-400M is a compact, dual-frequency multibeam echosounder built for hydrographic surveys. Designed for conditions where turbidity, depth variation, and vessel motion can affect data quality, it combines 400 kHz and 550 kHz operation, a 0.03° high-precision integrated IMU, and a lightweight 3.5 kg form factor for rapid USV deployment. From channel dredging and port inspection to river and lake surveys, it delivers reliable bathymetric data with no calibration required during installation.
