HN-400M Multibeam Echosounder
The CHCNAV HN-400M is a compact, dual-frequency multibeam echosounder designed for accurate and efficient hydrographic surveying. Operating at 400 kHz and 550 kHz, it combines a high-precision integrated IMU with 0.03° accuracy and a lightweight 3.5 kg design for quick and easy deployment on unmanned surface vessels (USVs). Built to deliver reliable bathymetric data in challenging conditions, including turbid waters, varying depths, and vessel movement, the HN-400M is well suited for channel dredging, port inspections, and river and lake surveys. Its calibration-free installation further simplifies setup and helps reduce time spent preparing for field operations.
