GeoSwath 4R Multibeam echosounder, Shallow water, Compact

GeoSwath 4R offers very efficient simultaneous swath bathymetry and side scan seabed mapping for small vessels. Accuracies have been shown to exceed the IHO standards for hydrographic surveys.

The applied phase measuring bathymetric sonar technology provides data coverage of up to 12 times the water depth, giving unsurpassed survey efficiency in shallow water environments. Its splash proof deck unit was designed to be deployed on small vessels like dinghies and jet skis equipped with a 24 V power supply.

System components

250 kHz single head transducer.

The GeoSwath 4R turn-key solution comprises a dual transducer head and a splash protected deck unit containing the complete sonar electronics, which can be interfaced via an Ethernet connection to the control laptop PC running the GeoSwath Plus survey software suite.

Dual Transducer wet end

The compact dual transducer sonar head assemblies are available in three frequency versions, 125, 250 and 500 kHz.

Deck Unit

The compact splash protected housing contains the complete system electronics. All peripheral sensors (position, motion, heading, transducer face sound velocity, sound velocity profiler and tide) are interfaced directly via IP66 rated connections.


Operating on Windows the GS+ software package provides a complete project based solution, including control, acquisition, storing and editing of sonar and ancillary data, grid-based patch test calibration, data processing with audit trail, advanced bathymetry data gridding and side scan mosaicing, data visualisation including 3D fly-through capability. Depending on the survey situation full online data processing can be performed or the operation can be limited to basic acquisition start and stop commands.
