Innomar "light" Sub-Bottom Profiler

Innomar "light" SBP

Innomar "light" SBP

The Innomar "light" sub-bottom profiler is designed for shallow-water applications inshore and near-shore at water depths down to 400 meters.

This 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.

The first generation of this model has been launched in 2000 as "SES-96 light". Later this model were named "SES-2000 light". The latest generation has been introduced in 2021.
