For 15 years, Teledyne RD Instruments’ Workhorse Acoustic Doppler Current Profilers have been the world’s gold standard for measuring ocean currents and waves. Now, our next generation V line of ADCP products raises the bar again. The new Sentinel V is the first product to be released from this emerging line. This self-contained instrument is available in three profiling ranges: 20m, 50m, and 100m.
