The Furuno FCV628 Fish Finder uses RezBoost™ the capabilities of conventional narrowband transducers can be dramatically improved. Compared to conventional signal processing techniques (FDF), a RezBoost™ fish finder 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. What can be done with a conventional narrowband transducer, just like the one you might have installed on your vessel, is truly impressive*2.
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 sh surrounding bait balls, as well as sh close to the seabed. With RezBoost™, not only can you expect higher resolution and crisper visuals, but also improvements in the ACCU-FISH™ function.
