Combining unparalleled sensitivity and the reliability you expect, the Argonaut-MD (Mooring Deployment) acoustic Doppler current meter has become the instrument of choice in the oceanographic community. Capable of measuring water motion at a "single point" almost anywhere in the oceans, this 3-D, vector-averaging current meter is small, light, and inexpensive. The MD’s high-sensitivity transducers improve performance in environments that have exceptionally low scattering conditions. The MD's simple, yet elegant design, and its capacity for long-term deployments provide you with accurate, dependable ocean current data.
