Why the Furuno DFF3D Is a Game Changer
The DFF3D turns your Furuno system into a wide-angle 3D sonar setup, letting you see fish movement and structure across a massive area in real time.
- 120° port-to-starboard sonar coverage
- Track fish direction and movement
- Locate bait schools before they pass under the boat
- Visualise reef edges, ledges and drop-offs
Who This System Is For
- Offshore and game fishing boats chasing pelagics
- Serious anglers wanting wide-area fish detection
- Boaties upgrading from traditional sounders
- Skippers targeting reef, bait and structure zones
Real Performance on the Water
The DFF3D delivers wide and deep coverage in a way traditional sounders simply can’t match.
- Up to 120° scanning coverage across the water column
- Side scanning out to approx. 200m either side
- Depth penetration to around 300m below the boat
This means you find fish faster, understand movement better, and spend less time guessing.
