Innomar SES-2000 medium-70 SBP

Innomar SES-2000 medium parametric sub-bottom profiler (top side unit)

The Innomar SES-2000 medium-70 parametric sub-bottom profiler is designed for offshore applications down to 2,500m water depth.

This model is available in two versions. The basic version features heave and roll compensation while the "POM" version offers additional pitch compensation.

The Innomar SES-2000 medium-70 SBP 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.
