Dual-Frequency Operation
The HN-400M enables seamless switching between 400 kHz and 550 kHz. The 550 kHz mode supports high-resolution shallow-water surveys, while 400 kHz with FM chirp improves penetration in deep and turbid conditions. One system supports consistent performance from inland lakes to offshore environments.
0.03° High-Precision IMU
The integrated IMU provides centimeter-level real-time motion compensation. It suppresses vessel roll, pitch, and heave, reducing data drift and preventing broken survey lines in offshore harbors up to Sea State 3. The HN-400M ensures continuous and reliable data acquisition in rough conditions.
145° Wide Swath Coverage
With swath coverage up to 6 times the water depth, the HN-400M reduces the number of survey lines required and minimizes vessel transit time. The HN-400M improves survey efficiency, lowers operational costs, and enables comprehensive bathymetric coverage in a single deployment.
EasySail Android Software
EasySail provides a one-touch workflow for device connection, parameter configuration, data acquisition, and real-time preview. It simplifies field operations, reduces technical barriers, and supports efficient and consistent survey execution.
