Sonic2024・GeoSwath Plus

This system can map vast areas of sea floors and riverbeds with each pass.

AAC uses a variety of sounders in order to fully meet the requests of customers. 

 
SeaBat8101
 
This high performance sounder can scan underwater terrains as deep as 300 m.
Unlike earlier single beam systems, it acquires superficial data to a high degree of density and digitally processes all of it.

GeoSwath Plus
1. The wide swath (max. 12x the depth) greatly improves work efficiency.
2. Can acquire side scan data (acoustic reaction of sea floor) at the same time.  
3. Allows swatch angles up to 240˚ that can acquire data near to the water's edge in shallow sea areas.  
4. Data is high density, thus more reliable.
