Key Features:

  • Versatility: Direct reading or self contained, moored or moving, the Sentinel provides precision current profiling data when and where you need it most.
  • A solid upgrade path: The Sentinel has been designed to grow with your needs. Easy upgrades include bottom tracking, and directional wave measurement.
  • A four-beam solution: Teledyne RDI’s patented 4-beam design improves data reliability, improves data quality, and improves data accuracy.
  • Precision data: Teledyne RDI’s patented BroadBand signal processing delivers very low-noise data, resulting in unparalleled data resolution and minimal power consumption.

The self-contained Workhorse II Sentinel ADCP is Teledyne RD Instruments' most popular and versatile acoustic Doppler current profiler (ADCP) configuration, boasting thousands of units in operation in over 50 countries around the world.

By providing profiling ranges from 1 to 165m, the Workhorse II Sentinel ADCP is ideally suited for a wide variety of applications. The Workhorse II Sentinel also offers unbeatable precision, with unmatched low power consumption, allowing you to collect more data over an extended period.

The lightweight and adaptable Workhorse Sentinel is easily deployed on buoys, boats, or mounted on the seafloor. Real-time data can be transmitted to shore via a cable link or acoustic modem, or data can be stored internally for short or long-term deployments. 

Beginning in 2023, the Workhorse II models replace the original Workhorse models and include several improvements. These include increased memory in compact flash card, compass with improved performance and specifications (especially at higher latitudes and tilt angles); and raw magnetometer data for use in postprocessing. In addition, a 200m pressure sensor and water modes LADCP, Ice Tracking, Mode 11 and Mode 12 come standard and are not required to be purchased.
