Innomar "medium-70" Sub-Bottom Profiler

Innomar medium-70 parametric sub-bottom profiler

The Innomar 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 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 SBP data.

A new generation of this model has been launched in 2020. The topside unit's weight and size is reduced by more than 35%. The Innomar medium-70 model has been formerly also known as "SES-2000 medium-70" and "SES medium-70".
