Innomar SES-2000 light plus Sub-Bottom Profiler
and Dual-Frequency Sidescan Sonar

Innomar SES-2000 light plus parametric sub-bottom profiler with sidescan (top side unit and transducers) The Innomar SES-2000 light plus model acquires simultaneously sub-seafloor and sidescan data in shallow water.

A unique feature of this model is the integrated dual-frequency sidecan sonar. In total you get three data sets for each survey line: single-beam echosounder, sub-bottom and sidescan data.

All transducers are pole-mounted at the same location. Having just one reference point simplifies processing. No deployment or recovery of towed items is necessary, which reduces survey time and minimizes the probabilty of equipment damage or loss.

The Innomar SES-2000 light plus model acquires full-waveform SBP data that can be processed with any seismic software (SEG-Y format), sidescan data can be converted to XTF data format that can be processed with a wide range of third-party software. Innomar also provides the ISE post-processing software specialized on the Innomar SES-2000 SBP data.
