SES-2000 light Hardware

The system SES-2000 light is based on the SES-96 product line, which is the first mobile parametric sediment echo sounder on the international market.
The compact design with an user friendly control unit allows the survey even in small and shallow waters with all the advantages of the parametric acoustics, such as the small beamwidth at low frequencies, deep penetrations with high resolutions of layers and objects and very accurate depth measurements with the high frequency.
The system offers the possibility to store the data digitally but also gives  excellent and reliable results during the online processing .
