FURUNO FCV-628, 5.7″ Color LCD Fish
Finder with RezBoost and Accu-Fish

Fantastic clarity and target separation
with RezBoost™ technology!

The 5.7″ FCV628 uses revolutionary new RezBoost™
technology that increases resolution and improves target separation
utilizing a compact, narrowband transducer.

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 RezBoost™, not only can you expect higher
resolution and crisper visuals, but also improvements in the ACCU-FISH™

With 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 clearer. What can
be done with a conventional narrowband transducer, just like the
one you might have installed on your vessel, is truly impressive.

With RezBoost™ technology, the resolution
is increased, leading to sharper and more defined echoes. Thanks
to this increase in resolution, the accuracy of the ACCU-FISH™
function is also improved. ACCU-FISH™ is very useful when you need
to determine fish size, but also has the added benefit of making
fish echoes more visible when viewed from a distance. With ACCU-FISH™
you can spot individual fish echoes even from the deck on your vessel.

Recognize individual or multiple fish instantaneously!
ACCU-FISH™ is a fish size assessment function of FCV628 that is
proprietary to FURUNO. In order to assess individual fish size, echo
returns are evaluated based on strength and turned into fish size
display on screen. ACCU-FISH™ can detect fish size from 10 to 199
cm, in depths of 2 to 100 m.

The fish mark can be utilized to display
individual fish echoes when they are detected. It helps beginners
to identify fish echoes for a more engaging fishing experience. Fish
marks are selectable from either a circle or square, as well as,
two fish symbols. The fish symbols, displayed in two different sizes
(Large: over 50 cm, Small: 10 to 49 cm), are a great help for anglers
when identifying individual fish. The circle and square symbols identify
individual fish without hiding the underlying echo.

FCV628’s Bottom Discrimination function
enables the fish finder to indicate whether the bottom is composed
mainly of rocks, gravel, sand or mud. The Bottom Discrimination function
provides you with valuable information that helps you locate rich
fishing grounds, and boost your catch of the day. The White Line
function distinguishes fish from the seabed. This function is useful
for discriminating bottom fish as well as judging fish school density.

With the FCV628’s Fish Alarm function,
when fish echoes appear in an area preset by the user, the FCV628
will sound a loud alarm and display an alarm icon on-screen. The
integrated alarm can also be set to be triggered by specific conditions
for water depth, target depth, water temperature, bottom type and
more. You never have to miss a target again!
