Furuno DFF1 Digital (FDF) Black Box Echosounder Module for NavNet, Less Transducer (600W or 1KW)

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.
