Furuno DFF3D Network Multi Beam Sonar

The Furuno DFF3D Multi Beam Sonar is an innovative tool for efficient fish location and seabed profile surveying, utilizing new multi beam technology. Highly detailed images are derived from the combination of an advanced signal processing system and an amazingly compact multi beam transducer.

Furuno DFF3D multi beam sonar can see 120-degrees port to starboard, allowing you to see the depth and direction fish schools are moving, while displaying the seabed condition in real time.
