The DT-X SUB is a completely self-contained echo sounder solution for autonomous deployments where cabling to the surface may be cost-prohibitive or impractical. DT-X scientific echo sounder technology is packaged in a pressure rated housing that is adaptable for deployment via AUV, ROV, or seafloor observatory platform.


  • Long-term, self-contained, autonomous deployments
  • Seabed mount, mid-water mooring, surface buoy
  • Modular OEM integration with AUV, ASV, ROV platforms
  • Biological ocean observation
  • Fish size, distribution, and abundance
  • Marine mammal detection
  • Plankton distribution and vertical migration
  • School detection and single target detection
