CHCNAV D390 Integrated Single-Beam Echosounder
The D390 is a rugged, cost-effective bathymetric system combining a 200 kHz, 500 W echosounder with an industrial Windows PC and a 12″ touchscreen in one IP66 case.
A 7° beam gives focused resolution, depths are logged at up to 60 Hz, and pulse-width discrimination suppresses redundant data.

D390 Single-Beam Echosounder
CHCNAV D390 – single-beam echosounder with a built-in 12″ PC
The D390 is a rugged, cost-effective bathymetric system combining a 200 kHz, 500 W echosounder with an industrial Windows PC and a 12″ touchscreen in one IP66 case.
A 7° beam gives focused resolution, depths are logged at up to 60 Hz, and pulse-width discrimination suppresses redundant data.
Cut mobilization cost by 20%
HydroSurvey 7 manages projects from positioning and navigation to acquisition, processing and CSV export. Standard serial ports accept any NMEA GNSS RTK receiver and motion sensors, and the embedded Windows 10 boots fast for quick starts. In Alberta, RTK corrections can come from the LATNET RTK network over 4G. See how single-beam, multibeam and ADCP surveys work in our 3D animations.
Why choose the D390
High-performance sounding
200 kHz, 7° beam, up to 500 W.
Extended range
0.15–300 m.
Built-in PC
Windows 10, 4 GB RAM, 32 GB.
HydroSurvey
Navigation, acquisition and export in one app.
Any GNSS
Standard NMEA input, CHCNAV-optimized.
Rugged
Aluminium enclosure, –30 °C rated.
200 kHz transducer, 7° beam
The advanced 200 kHz transducer and focused 7° beam deliver precise depths in rivers, reservoirs and coastal water, with pulse-width discrimination and redundant-data suppression.
Up to 300 metres
Up to 500 W RMS output extends sounding to 300 m with ±0.01 m + 0.1% accuracy.
HydroSurvey on a 12″ screen
HydroSurvey 7 runs on the built-in PC: plan, navigate, log and export. Data is stored internally and copied by USB.
