The Portable Hydrographic System D390 is a cost-effective and rugged
bathymetric solution that uses an advanced 200 kHz transducer to match
different hydrographic conditions and significantly improve sounding
performance and usability. The 7-degree beam angle provides focused
directional and lateral resolution. In addition, the water depth
recording frequency can be as high as 60 Hz. Using pulse width
discrimination and automatic redundant data suppression enhance data
accuracy and reliability.
Easy to operate with its feature-rich CHCNAV HydroSurvey software, the
D390 clearly displays real-time depth readings and the survey project
parameters on its 12-inch HD touch screen. The standard serial
interfaces for motion sensors and GNSS differential receivers allow
centimeter position precision.
