Portable Multibeam Echo Sounder ECT 400Si<\/h1>\n

The Portable Multibeam Echo Sounder ECT 400Si<\/strong> is a professional MBES solution<\/strong> designed for coastal, riverine and estuarine bathymetric surveys<\/strong>. It provides high-resolution seabed mapping and reliable detection of submerged objects in shallow and near-shore environments.<\/p>\n

The system combines a wide-swath multibeam transducer with high-frequency acquisition electronics operating at a nominal 400 kHz<\/strong>. In addition, the agile frequency range allows optimal performance across different water depths and seabed conditions.<\/p>\n

Thanks to full integration with RTK positioning<\/strong>, motion sensors and professional survey software, the ECT 400Si delivers accurate, repeatable and georeferenced data. As a result, survey time and post-processing effort are significantly reduced while maintaining hydrographic-grade accuracy.<\/p>\n

Short description<\/h2>\n
