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 clearer.
