Furuno's DFF1 is a new network sounder featuring Furuno Digital Filter (FDF) Technology designed for use with NavNet and NavNet vx2. 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 600W or 1kW output power. You may choose LF (50kHz), HF (200kHz) or both at the touch of a key and obtain detailed echoes of bottom structure and fish using range scales of up to 5,000 ft. 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 DFF1 is a direct replacement for the BBFF1.
