NOW INTEGRATED WITH HYPACK®! [Learn more] The HydroSurveyor is a system designed to collect bathymetric, water column velocity profile, and acoustic bottom tracking data as part of a hydrographic survey. The two key components of the system are the HydroSurveyor Acoustic Doppler Profiler (ADP®) platform, and the powerful, yet user-friendly, data collection software. With the HydroSurveyor platform, SonTek is able to offer an exclusive 5-beam depth sounding device, with built-in navigation, full water column velocity (currents) profiling, full compensation for speed of sound (with the CastAway-CTD), and integrated positioning solution.
Features
Flexible and Fast.
Water sound speed corrections are interpolated in both space and time with the fully integrated CastAway-CTD.
All Inclusive.
Full water column velocity mapping, 5-beam depth sounding and acoustic bottom tracking (for speed over ground when GPS is lost) provide comprehensive data for a complete solution with a single package.
Software Centric.
With built-in automatic data gridding and interpolation, even intricate surveys will not require specialized complex software, saving you time and money.
