Wärtsilä ELAC SeaBeam 3050 N

Wärtsilä ELAC SeaBeam 3050 N is a highly advanced medium-depth multibeam system from Wärtsilä ELAC Nautik, collecting real-time bathymetric data, bottom amplitudes, side scan data and water column imaging (WCI) data.

Due to its depth performance, wide coverage and multi-ping operation, Wärtsilä ELAC SeaBeam 3050 N is the ideal sonar to detect static or moving underwater objects like submarines. It can be utilised as an additional sensor for submarine rescue operations or for submarine hunting in littorals.

Wärtsilä ELAC SeaBeam 3050 N is the ideal multibeam echo sounder to be adapted to specific naval requirements.
