The CHCNAV D390 Echo Sounder Package is a professional single-beam echo sounder system designed for hydrographic survey, bathymetric mapping, and water depth measurement applications. Delivering accurate, high-resolution depth data for rivers, lakes, reservoirs, coastal areas, and ports, the D390 is engineered for integration with GNSS receivers and unmanned surface vehicles (USVs) for efficient, georeferenced bathymetric data acquisition.Key Features Single-Beam Echo Sounder — High-accuracy single-beam depth measurement for hydrographic survey and bathymetric mapping applications GNSS Integration — Integrates with GNSS receivers for georeferenced depth data acquisition, enabling direct GIS and hydrographic processing workflow integration USV Compatible — Designed for integration with unmanned surface vehicles for autonomous or remotely operated bathymetric surveys in shallow, confined, or hazardous water environments Wide Depth Range — Suitable for shallow inland water surveys through deeper coastal and port applications Real-Time Data Output — Real-time depth data output for live monitoring and quality control during survey operations Applications River, lake, and reservoir bathymetric mapping Coastal and port hydrographic survey Dredging volume calculation and monitoring Flood risk assessment and channel mapping Infrastructure inspection (bridge piers, dam foundations, underwater structures) Environmental monitoring and sediment survey
