DFF1 600/1,000 Watt Sounder Black Box
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.
Connects to any Transducer with Furuno 10 Pin Plug
The DFF1 is a direct Digital replacement for the Analog BBFF1
