SeaBeam 3030/3050
Medium Water Depth Multibeam Echo Sounders
Description
The latest generation medium-depth multibeam systems from Wärtsilä ELAC Nautik, collecting real-time bathymetric data, bottom amplitudes, side scan data and water column imaging (WCI) data. Due to their depth performance, wide coverage and multi-ping operation, Wärtsilä ELAC SeaBeam 3030 and ELAC SeaBeam 3050 are the ideal hydrographic sensors for mapping the continental rise and slope.
