Teledyne Workhorse II Mariner: Vessel-Mounted ADCP

Precision Current Profiling and Bottom Tracking for Coastal & Research Vessels

Product Overview The Workhorse II Mariner is the latest evolution of Teledyne RDI’s world-renowned vessel-mounted Acoustic Doppler Current Profiler (ADCP). Specifically engineered for moving boat applications, the "Mariner" is designed for permanent or temporary hull-mounting, providing real-time, high-resolution current profiles from shallow coastal waters to the edge of the continental shelf.

The 2nd Generation (Workhorse II) refresh brings significant hardware and software improvements to the classic Mariner platform. It combines Teledyne’s patented BroadBand signal processing for low-noise data with a new, more robust electronics suite, increased memory, and an enhanced compass for superior performance at high latitudes.

Why Choose the Workhorse II Mariner?

  • Patented 4-Beam Design: Improves data reliability by providing a redundant data source and a dedicated "error velocity" measure to ensure data quality in real-time.
  • Convenience & Protection: By installing the Mariner directly into the hull, the unit is always ready for operation, requires no cumbersome deployment hardware, and is protected from external damage.
  • Integrated GNSS Compatibility: Seamlessly integrates with the vessel’s GPS/GNSS and gyro inputs to provide absolute current velocity data with precise geo-referencing.
  • BroadBand Precision: Delivers exceptionally low-noise data, allowing for unparalleled fine-track resolution and higher data density than narrowband systems.
  • Workhorse II Upgrades: Includes a 200m pressure sensor as standard, plus built-in support for Ice Tracking, LADCP, and high-resolution water modes at no additional cost.
