DT-X Extreme Autonomous Portable Scientific Echosounder

The DT-X Extreme is an innovative and versatile echosounder system that expands your data collection opportunities. Operate the DT-X Extreme as a portable system for mobile surveys, or as a fully autonomous system, ideal for ASV/USV surveys, surface buoys and other unmanned deployments, or for fixed location monitoring applications. The DT-X Extreme produces accurate, high resolution water column data and results for fisheries management and research, to study communities of biological organisms and physical elements of marine and freshwater ecosystems, including fish schools and individuals, plankton, nekton, mammals, birds, debris, oil droplets, gas bubbles and more.
