The SOUTH SDE-28S+ is a professional single-frequency digital echo sounder designed for precise depth measurement and hydrographic surveying. Rugged, integrated, and easy to operate, it is ideal as an echo sounder payload for USVs and small survey vessels.
The SDE-28S+ integrates an industrial-level echo sounder, control unit, data processor, and a 12.1-inch TFT-LCD display into a single, robust instrument. Built for demanding environments, it is waterproof, dustproof, and shock-resistant, making it suitable for hydrographic surveys in rivers, lakes, coastal waters, and reservoirs.
Equipped with onboard software for depth visualization and real-time data tracking, the SDE-28S+ allows operators to monitor water depth and seabed profiles directly. Integrated sound velocity correction and smart alarms ensure reliable operation even in shallow or challenging conditions. It also supports GNSS and navigation input via standard interfaces for georeferenced surveys.
Why It Matters: Accurate depth measurement is essential for hydrographic mapping, dredging control, and environmental studies. The SOUTH SDE-28S+ provides dependable, high-resolution depth data that enhances survey precision when integrated with USV platforms like the Aqua M20 and Aqua M20 Pro. At GeoExpert, we provide trusted hydrographic sensors that deliver professional results for every water survey project.
