High resolution fish echoes with RezBoost™ technology. FCV-628 uses revolutionary new RezBoostTM technology, providing an incredible boost in resolution and target separation, utilizing a compact narrowband transducer. With RezBoostTM the capabilities of conventional narrowband transducers can be dramatically improved. Compared to conventional signal processing techniques (FDF), a RezBoostTM fish finder produces an image that is up to 8 times*1 clearer. A TruEcho CHIRPTM fish finder (requires a special transducer) produces an image that is up to 10 times 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.
