- Model SES-2000 Medium-70 - Parametric Sub Bottom Profiler


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 SES-2000 data.
