ELAC HydroStar 4900 Survey Echo Sounder

HydroStar 4900 is a high precision (0.25% of depth) modular survey sounder for hydrographic and commercial survey vessels. Data are presented on a high-resolution color monitor as echogram and by numerical values. Due to its digital signal processing, HydroStar 4900 allows exact bottom detection and bottom penetration.
The echo sounder can be operated with up to four transducers with different frequencies. It processes and visualizes position and ambient data such as temperature, density, salinity and sound velocity and can be remote-controlled via LAN.
