Innomar "compact" Sub-Bottom Profiler

Innomar "compact" SBP

Innomar "compact" SBP

The Innomar "compact" model was designed for inshore surveys in shallow-water down to 400 metres water depth, but can also be used in coastal areas.

Because of its small size and weght this system is convenient even on small boats. Controlled via Ethernet using any Windows based PC or laptop it is a user friendly and affordable design, too. For this SBP model there is a Sidescan Extension available.

The Innomar "compact" 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.

This model has been first launched as "SES-2000 compact" in 2002, the latest generation has been introduced in 2021.
