HN-400M Multibeam Echo Sounder System
Model:HN-400M
The HN-400M is Chinas New Generation Multibeam Echosounder, designed to overcome critical challenges such as poor turbidity penetration, depth data drift in deep waters, and severe vessel motion in coastal ports. With its three core advantages—intelligent dual-frequency switching, high-precision inertial navigation for attitude stabilization, and lightweight, easy-to-integrate design—it delivers a comprehensive, highly reliable, and precise underwater terrain mapping solution for coastal surveying, underwater engineering inspections, channel dredging, and inland waterway mapping.
