Fantastic clarity and resolution with RezBoost™ technology!

RezBoost™ is a revolutionary new signal processing technology developed by FURUNO that improves resolution and target separation when using conventional narrowband transducers. Spot individual game fish surrounding bait balls, as well as fish close to the seabed. With the dual-frequency (50/200 kHZ) RezBoost™ technology, not only can you expect higher resolution and crisper visuals, but also improvements in the ACCU-FISH™ function.

With RezBoost™ the capabilities of conventional narrowband transducers can be dramatically improved. Compared to conventional signal processing techniques (FDF), a RezBoost™ sounder produces an image that is up to 8 times*¹ clearer. A TruEcho CHIRP™ Fish Finder (requires a special transducer) produces an image that is up to 10 times*¹ clearer when compared with FDF. However, what can be done with a conventional narrowband transducer and RezBoost™, just like the one you might have installed on your vessel, is truly impressive*².

^*1 RezBoost™ performance may vary depending on depth, range and signal frequency used.
^*2 The Enhanced mode of RezBoost requires a RezBoost capable thru-hull or transom mount transducer.

Easily identify the makeup of the seafloor with Furuno's exclusive Bottom Discrimination mode

The Bottom Discrimination mode enables the Fish Finder to indicate whether the bottom is composed mainly of rocks, gravel, sand or mud. This provides you with valuable information that helps you locate rich fishing hot spots, and boost your catch of the day.

Please keep the following in mind when using the Bottom Discrimination mode:

1. Use at a depth of 16.5 feet (5 meters) to over 320 feet (100 meters)
2. Use a transom or thru-hull bottom discrimination transducer from the list below
3. Install the transducer parallel to the bottom of the vessel
4. To show a consistent display of the actual bottom, set the display range to "auto"
5. Enter the ship's draft value
6. Use a ship speed of 10 kn or less
7. In some instances, the bottom component indicated my differ from the actual bottom structure

Please read the operator's manual carefully before using this feature
