CHCNAV HN-400M Multi-Beam Echosounder
type: Product
description: CHCNAV HN-400M Dual-Frequency Multibeam Echosounder The CHCNAV HN-400M is a lightweight, fully integrated dual-frequency multibeam echosounder built for high-resolution bathymetric and hydrographic surveys in challenging waters. Combining a 400 kHz / 550 kHz sonar, high-precision INS-based motion stabilization, GNSS positioning, and surface sound velocity sensing in one compact unit, it delivers dependable underwater mapping from inland lakes and rivers to coastal and offshore environments. With 512 receive beams, a 145° swath coverage (up to 6 times water depth), and 0.03° roll and pitch accuracy, the HN-400M captures dense, full-coverage bathymetric data even where turbidity, depth variation, and vessel motion would compromise conventional systems. Its 400 kHz FM chirp mode penetrates deep and turbid water down to 200 m, while the 550 kHz mode resolves fine detail for precision shallow-water work — one system for every environment. Built for real-world deployment, the system weighs just 3.5 kg, installs calibration-free, and mounts in minutes on USVs such as the APACHE 4, APACHE 4 Pro, and APACHE 6, or on manned vessels via a mounting bracket. The EasySail Android app puts vessel control, acquisition, parameter setup, and real-time 3D preview in one touch — no field computer required. Why Choose the CHCNAV HN-400M? The HN-400M stands out as a smarter, more adaptable multibeam solution for professionals surveying difficult waters. Intelligent dual-frequency operation, an integrated 0.03° IMU, and roll-stabilized beam steering keep data quality high in waves up to 1 m on USV platforms. Setup that traditionally takes 3 hours is done in 30 minutes, and a complete survey can be run by a two-person crew. Upgrade your hydrographic capability with the CHCNAV HN-400M and cover more water, in more conditions, with cleaner deliverables and faster mobilization.
