TELEDYNE RD INSTRUMENTS –

WORKHORSE PROTEUS ADCP ture; hydrology and ? ood warning; and renewable energy.

Proteus continues RDI’s proven track record of over 40 years of data quality and reliability. Its technical advantages deliver the most data possible with a single instrument, both in terms of useable data per ping and the number of differ- ent ways a single system can be used. With the processing horsepower to simultaneously sample at multiple spatial and temporal scales, Proteus can unlock a new understanding of waves, turbulence, and the changing currents below the surface. Proteus has RDI’s reliable bottom-tracking velocity ping to allow moving boat surveys or ice keel tracking while also taking advantage of a very low power sleep state to al- low multi-year durations on alkaline battery power. It has ? exible onboard processing to allow sampling schemes to continue to evolve in response to a changing ocean.

Features of Proteus include Advanced Doppler Sonar
