Furuno DFF3 Black Box Sounder Module
Furuno’s DFF3 is a new network sounder featuring FDF (Furuno Digital Filter) signal processing technology. The DFF3 is designed for use with NavNet, NavNet VX2 and NavNet 3D. This new digital Network Sounder can turn any NavNet display into a powerful, dual-frequency digital fish finder. The compact network sounder unit connects directly to a NavNet display or an Ethernet hub with a single Ethernet cable. If it is connected to an Ethernet hub that has multiple displays attached, each of those displays will have access to the Network Sounder.

The sounder itself has a selectable 1, 2 or 3kW output power. You may choose any two operating frequencies from 28 to 200 kHz with FFS (Furuno Free Synthesis) technology. With the powerful DFF3, you can obtain detailed echoes of bottom structure and fish using range scales of up to 3,000 meters (nearly 10,000 feet). And because the Network Sounder is used on a NavNet display, you will also be able to use its Radar and Chart Plotter features depending on which unit you have.

The DFF3 is a direct replacement for the BBFF3 network sounder.
