DT-X Portable EchosounderDigital Scientific Portable Echosounder

Learn the Basics

The BioSonics DT-X Digital Scientific Echosounder is the industry standard used by hundreds of researchers and resource managers worldwide. The DT-X is suitable for a wide range of fisheries and oceanographic assessment applications including fish stock assessment, bathymetric surveying, substrate classification, and submersed aquatic vegetation mapping. The portable and rugged design makes it suitable for deployment from most any vessel working in any aquatic environment, from remote mountain lakes to arctic research vessels.

DT-X Digital Scientific Echosounder

Some of the unique features of the DT-X include:

  • Multi-channel, multi-frequency capabilities (with no additional components required)
  • Digital transducers for improved signal-to-noise ratio and overall superior data quality
  • Extremely low side lobe transducers (~ -30dB)

How It Works

  • Electrical energy converted to sound
  • Sound transmitted through water, focused on axis
  • Sound is reflected by objects with different density than water
  • Reflected energy is converted by transducer from mechanical to electrical
  • Sound velocity used to convert time-based data into range-based data
  • Echosounder receiver amplifies signal and provides quantitative output (display and raw acoustic data)

The components of a complete DT-X echosounder typically include:

  • DT-X Digital Scientific Echosounder surface unit
  • Laptop computer with BioSonics Visual Acquisition data collection software (we recommend Panasonic Toughbook Computers for the ultimate in reliable performance in outdoor conditions)
  • One or more DT-X Digital Transducers with Digital Signal Cables
  • DGPS sensor
  • Transducer Mount or a BioFin Towing Vehicle
  • Calibration Sphere (tungsten carbide)
