SonTek HydroSurveyor™

The HydroSurveyorTM 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.

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.
