Innomar "light" Sub-Bottom Profiler

Innomar light parametric sub-bottom profiler 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.

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

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