DFF3D
2019 NMEA Product of Excellence Award Winner!
Visibly see the landscape and fish schools at great depths in amazing detail
Multi-beam sonar for deep and wide water columns
Furuno’s DFF3D takes 3D Fish Finding to new depths. Main beam penetration directly under the boat is approximately 300m, with Side Scanning up to 200m. See fish and bottom structure as you’ve never seen them before, at depths previously unfathomable.


Easily see where to drop lines
When you find fish, you can quickly drop a mark on your Chart Plotter for a return drift. Then looking at the DFF-3D’s Cross Section and Side Scan Modes (right side of the screen), you can easily determine which side of the boat the fish are on, how deep they are, and how far out from the boat they are swimming.
Customise the display according to your needs
Depending on the situation and preference, a combination of screen modes can be displayed.
Cross Section Mode
Displays real-time sea column echo in 120 degrees port-to-starboard. This mode instantly aids in understanding the distribution of bait fish and the water column condition.
Intuitive 3D Sounder History
The 3D sounder history provides an intuitive and easy to understand 3D image of the seafloor, along with fish school icons. This mode is useful in a variety of situations, such as selecting a fishing hot spot and assessing the seabed condition.
Side Scan
Side scan clearly displays the shape of structure as a high definition image in port and starboard direction.
It is suitable for searching the seabed and understanding the sea floor structure.
Note:
-
Satellite Compass required as the primary source of position, heading, and motion (roll/pitch/heave) data.
-
The DFF-3D can detect and generate a PBG database down to 200 m. When the depth is deeper than 200 m, the PBG source can be switched from the DFF-3D (multi-beam) to a Fish Finder (single beam).
