System Variants: SES-2000 deep

SES-2000 deep Hardware

The system SES-2000 has all the advantages of the parametric acoustics, like 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 has the possibility to store the data digitally but gives also during the online processing excellent and reliable results.

The variant SES-2000 deep is designed for deep water depth applications in ocean areas down to 8000m.
