The unit itself can be configured as a 1, 2 or 3 kW RMS output, dual frequency sounder. You may choose low frequency, high frequency or both at the touch of a key and obtain detailed echoes of bottom structure and fish using phased range scales up to 2,400 meters. It also utilizes Furuno's Free Synthesizer (FFS) transceiver which means you can easily select from a broad range of frequencies.
The BBFF3 turns any NavNet display into one of the most powerful fish finders available on the market today. And because it is being used on a NavNet display, you can split the screen with other NavNet features like: Radar, Chart Plotter, NavData and even Video, depending on which NavNet unit you have.
