The BioSonics DT-X  Digital Scientific Echosounder is designed for a wide range of fisheries, marine life and oceanographic assessment applications.  For over thirty years, BioSonics scientific echosounders have been used in oceans, lakes, rivers, and at hydropower dams, estuaries, navigation locks, or anywhere accurate assessment of fish abundance, distribution or behavior is required.  The portable, versatile and rugged design makes it suitable for use in every aquatic environment imaginable, from remote mountain lake deployments to permanent multiple transducer deployments on marine research vessels.  Physical oceanographers also use our systems to study ocean mixing and a variety of other physical properties.

The BioSonics DT-X Digital Echosounder System used in combination with BioSonics EcoSAV data processing software is the only commercially available hydroacoustic system specifically designed for submerged aquatic vegetation (SAV) assessment.

Researchers and submerged aquatic vegetation resource managers use the BioSonics DT-X Echosounder System and BioSonics EcoSAV to assess numerous species of submerged aquatic vegetation in both marine and fresh water environments.  Common uses include locating and quantifying critical habitat species such as eelgrass for protection purposes, and calculating accurate canopy heights and densities of invasive species such as Eurasian Watermilfoil.
