Innomar SES-2000 compact Sub-Bottom Profiler

Innomar SES-2000 compact parametric sub-bottom profiler The Innomar SES-2000 compact model 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 small boats. 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 SES-2000 SBP data.

For survey examples please see also Extremely Shallow Water Applications and Shallow Water Applications.

For the Innomar SES-2000 compact SBP model there is a Sidescan Extension available.
