Innomar - Model Innomar Essential Series -Sub-Bottom Profiler (SBP)

Wave-induced vehicle movements are compensated for by using heave compensation and optional electronic beam stabilisation. These functions require motion data from an external sensor (not included).

The "Innomar essential" SBP model is optimised for easy integration. All the transceiver electronics are integrated within the SBP transducer. The depth rating is 100 metres.

As with all Innomar SBPs, a user-friendly Windows data acquisition and system control software (SESWIN) is used for operation. The "Innomar essential" model acquires full-waveform data that can be processed in SEGY format using any seismic software. Innomar also provides the ISE post-processing software that specialises in Innomar SBP data.
