Furuno DFF3D Multi-Beam Sonar Module

Furuno DFF3D Multibeam Sonar Module transforms NavNet TZtouch or TZtouch2 MFDs into a sophisticated 120-degree multi-beam sonar system, giving anglers and professionals real-time insight into depth, fish movement, and seabed structure.

• 120° water-column and seabed view: Real-time cross-section from port to starboard with side-scan imaging to quickly assess fish activity and bottom conditions.
• Deep-water penetration: Main beam reaches over 1,000 ft (350 m) directly under the boat, with performance dependent on water conditions.
• Flexible transducer options: Thru-hull or transom-mount transducers to suit a variety of vessels and installation needs.
• Real-time 3D seabed and fish imaging: 3D sounder history provides intuitive seabed visuals with fish icons for hotspot planning.
• Display modes for comprehensive viewing: Triple/single beam, Side Scan, Cross Section, and 3D sounder history—display combinations can be tailored to the situation.
• Stabilized imagery: Built-in motion sensor stabilizes the display for clear, steady images even in rough sea conditions.
• Beam options and angles: Triple-beam sounding with selectable beam angles (20–50° from right under the boat) for detailed target and bottom analysis.
• Connectivity: LAN 1 port (10/100BASE-TX) and an external KP port for optional control panels.
• Power and compatibility: Operates on 12–24 VDC with a current draw of 1.4 A (active) / 0.7 A (standby).
• What’s in the box: DFF-3D Multibeam Network Sonar, FGBO fuse 5A x 2, M5 x 20 tapping screws x 4, 5 m network cable, and power cable assembly.

With the DFF3D, you can quickly identify productive fishing areas in deep water by correlating depth, fish movements, and seabed structure in real time. The stabilized, multi-angle views help you understand where baitfish are concentrating and how the water column conditions change, while flexible installation and display customization let you adapt the system to your vessel and fishing style. Whether you’re mapping seabed features, targeting moving schools, or planning bait deployments, the DFF3D provides actionable insights straight from your NavNet MFD.
