Wärtsilä ELAC SeaBeam 1180

Wärtsilä ELAC SeaBeam 1180 is a well-recognised and proven multibeam echo sounder. It collects bathymetric, side scan and backscatter data in very shallow waters with beams as narrow as 1.5 x 1.5 degrees and a swath width in excess of 150 degrees.

The system is com­pletely roll-stabilised and guarantees high-preci­sion survey results.

Wärtsilä ELAC SeaBeam 1180 is ideally suited for highly de­manding surveys in shallow waters of up to 600 metres and in areas of extreme sedimentations, e.g. for river and port authorities, for research institutes or in onshore survey operations, e.g. in lakes.
