Furuno DFF3 Network Sounder

The DFF3 is designed to integrate with Furuno NavNet and NavNet TZtouch series displays. It connects via a single Ethernet cable, allowing you to view sonar data directly on your existing multi-function display.

The DFF3 is compatible with a wide variety of transducers, but because it supports selectable power outputs up to 3kW and dual frequencies, you must ensure your chosen transducer is rated to handle your desired power and frequency settings.

With the correct transducer and the 3kW output setting, the DFF3 is capable of reaching depths of up to 3,000 meters, or nearly 10,000 feet. This makes it a robust choice for deep-water offshore fishing.

FDF technology processes the sonar signal to filter out surface noise and clutter while sharpening the return of fish targets. This results in a much cleaner, high-definition image on your display, making it easier to distinguish fish from the bottom structure.

Yes, the DFF3 features selectable output power of 1kW, 2kW, or 3kW. You can adjust this setting depending on your depth requirements, using lower power for shallow water to reduce clutter and higher power for deep-sea exploration.

The white line feature helps you identify fish that are holding tight to the bottom. By displaying the top edge of the bottom structure in white, it creates a clear contrast that makes it easier to spot fish echoes that would otherwise blend into the seabed.
