Acoustic Doppler Profiler (ADP®)

Product Name:Acoustic Doppler Profiler (ADP®)
Description:The SonTek Acoustic Doppler Profiler (ADP) is a high-performance, 3-axis (3D) water current profiler that is accurate, reliable, and easy to use. The ADP uses state-of-the-art transducers and electronics designed to reduce side-lobe interference problems that plague other current profilers.
