System Variants: SES-2000 compact

SES-2000 compact Hardware

The system SES-2000 compact is based on the SES-96 product line, which is the first mobile parametric sediment echo sounder on the international market.
This system variant has a size of one half of a 19" device only. It is therefore very compact, light weight and usable even on the smallest vessel. Controlled via an USB interface with any external PC or Notebook running MS Windows it is a user friendly design too. It has not all features of the SES product line, but nevertheless it uses the same advanced technique of parametric acoustics and the user can benefit from all the known advantages, like small beam width, high resolution combined with deep penetration and accurate bathymetry measurements. The compact design without integrated industrial PC components results in a very affordable and reliable instrument for sub-bottom profiling applications.

The variant SES-2000 compact is designed for shallow water depth applications near the shore and inland waters down to 400 m.
