Furuno Furuno's DFF3 is a network sounder featuring Furuno Digital Filter (FDF) Technology designed for use with NavNet, NavNet vx2, and NavNet 3D. FDF makes the picture clearer and easier to discriminate between baitfish and larger target species. It can turn any NavNet display into a powerful, dual-frequency digital fish finder. The unit connects directly to a NavNet display or an Ethernet hub with a single Ethernet cable. If 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. With FFS (Furuno Free Synthesis) technology you may choose any two operating frequencies from 28 to 200kHz. With the powerful DFF3, you can obtain detailed echoes of bottom structure and fish using range scales of up to 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.
