SonTek Argonaut®-XR ADCP

SonTek Argonaut®-XR ADCP


Multi-cell Doppler Current Profiler

The Argonaut-XR offers exceptional value for near shore deployments in less than 40 m of water. Designed specifically for mounting on the bottom of a river, channel, or harbor, the XR features a special mode that automatically adjusts one of its measurement cells for changing water level. Its small size, rugged build, and flexible system architecture make the XR attractive for both real-time operation and autonomous deployments.



  • MultiCell feature – 10 water velocity cells plus an eleventh automatically adjusting cell (AutoTide feature – see illustration above)
  • 3D water velocity
  • Integrated piezoresistive pressure sensor
  • Reflected echo intensity output
  • SDI-12
  • Mounting plate for easy installation
  • RS-232 communication protocol
  • ViewArgonaut Windows software for real time data collection, data retrieval, deployment, diagnostics and processing
  • Flexible sampling strategies for reduced duty cycle operation
  • Internal memory (stores over 20,000 samples)
  • Compass/two-axis tilt sensor
  • Temperature sensor on exposed titanium pin for fast response


  • External battery pack for autonomous operation
  • Integrated CT sensor

The MultiCell Feature

MultiCell is an innovative way of current profiling. Combining all the benefits of classical current profiling with the dynamic AutoTide feature, users have the best of both worlds. The Additional dynamic velocity cell adjusts with changes in water level.
