Innomar Technologie GmbH

- Model SES-2000 - Sub Bottom Profiler


The 'Innomar SES-2000 compact' model is the smallest member of the 'Innomar SES-2000' sub-bottom profiler family. It was designed for inshore surveys in shallow-water down to 400 metres water depth, but can also be used in coastal areas.

Because of its small size and weght this system is convenient even on the smallest boat. Controlled via Ethernet using any Windows based PC or laptop it is a user friendly and affordable design, too.

The 'Innomar SES-2000 compact' model acquires full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SBP data.
