Furuno FCV 628 uses revolutionary new RezBoost™ technology, providing an incredible boost in resolution and target separation, utilizing a compact narrowband transducer. Improved clarity and resolution that was previously impossible with conventional narrowband transducers has been made possible thanks to the new RezBoost™ technology.
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 (sold separately) is truly impressive.

Thanks to this increase in resolution, the accuracy of the ACCU-FISH™ function is also improved.


ACCU-FISH™ - A unique fish size analyzer based on the latest digital technology.  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 Furuno FCV 628 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.

Bottom Discrimination - Analyze Bottom StructureProvides an at-a glance recognition of bottom composition with four types of graphical displays (Rocks/Sand/Gravel/Mud) when connected to a supported thru-hull or transom mount transducer.
White line characteristic: Difference of fish near the bottom. The upper edge of the bottom echo is shown in white to clearly demonstrate the lower structures. This feature helps differentiate between weeds and bottom fish.
Configurable alarm function (depth, echoes of fish, etc.). With the Furuno 628 Fish Alarm function, when fish echoes appear in an area preset by the user, the Furuno FCV 628 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!
Share and display information on a chart plotter*. FURUNO's TLL (Target Lat/Lon) output allows you to interface the FCV-628 with your FURUNO chart plotter so that you can mark fishing grounds with various information (L/L, Depth, Water Temp, Fish size and Bottom type).
