Furuno DFF3-UHD High Power True Echo Chirp & Multi Freq

Furuno DFF3D UHD High Power True Echo CHIRP Multi-Frequency Sonar

The Furuno DFF3D UHD is a high-performance offshore multi-beam sonar module designed for serious anglers who want wide-area seabed mapping and detailed structure imaging. Built for offshore conditions, the DFF3D system scans port to starboard and directly below the vessel, giving a real-time 3D view of reef edges, drop-offs and fish holding structure.

Unlike traditional CHIRP fish finders that show only what’s directly beneath your hull, the Furuno DFF3D multi-beam sonar sweeps wide across the seabed, building a 3D image of underwater structure in real time.

• Multi-beam wide-area scanning
• True 3D bottom mapping
• High-power offshore performance
• Integration with compatible Furuno MFD systems
• Exceptional target separation

Offshore Performance You Can Trust

For offshore boats working 60–300 metres and beyond, bottom clarity and structure awareness matter. The DFF3D system provides a tactical advantage by revealing:

• Reef edges and pressure points
• Drop-offs and seabed contour changes
• Fish holding off to the side of the vessel
• Seabed texture and relief

This allows more precise boat positioning and more productive fishing time.

Installation & Transducer Setup Matters

The Furuno DFF3D requires correct transducer pairing and precise hull placement. Incorrect installation can significantly reduce coverage and clarity.
