FCV-588 8.4"Color LCD Fish Finder

High resolution fish echoes with RezBoost™ technology!

FCV-628 uses revolutionary new RezBoost™ technology, providing an incredible boost in resolution and target separation, utilizing a compact narrowband transducer.

Newly employed digital filter can achieve
The main bang (echo just below the transducer) is suppressed to less than 40 cm so that the fish echoes below the transducer can easily be observed.
Two types of Auto Mode available: Cruising and Fishing
Fast pulse transmission rate to achieve outstanding shallow water echo presentation
Dual frequency 50/200 kHz
High output power of 600 W
TLL output for an interfaced GPS plotter display
5.6" sunlight viewable bright 256 color LCD with a wide viewing angle
Echo presentation in 8/16/64 color gradation
Customized NAV data display when interfaced with appropriate sensors
New design that allows the display unit to swivel around when table-top mounted
Easy to flush mount
Easy to operate by two rotary knobs for gain control and mode changes

RezBoost™

Dual-frequency fish finder equipped with revolutionary new RezBoost™ signal processing technology

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™ function RezBoost™ 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.
A TruEcho CHIRP™ 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**.

* RezBoost™ performance may vary depending on depth, range and signal frequency used.
**The Enhanced mode of RezBoost requires a RezBoost capable thru-hull or transom mount transducer.

ACCU-FISH™

A unique fish size analyzer based on the latest digital technology

Recognizes individual or multiple fish instantaneously ACCU-FISH™ is a fish size assessment function of FCV-588 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 100m.

Display fish marks

The fish mark can be utilized to display individual sh echoes when they are detected. It helps beginners to identify fish echoes for a more engaging shing experience. Fish marks are selectable from either a circle or square, as well as, twofi sh 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 sh without hiding the underlying echo.

Bottom Discriminator

The Bottom Discrimination feature enables the fishfinder to indicate if a major component of the bottom is mud, sand, gravel or rocks. The Bottom Discrimination Function provides you with valuable information to locate rich fishing grounds, while boosting your catch of the day.

Please keep the following in mind when using the Bottom Discrimination Sounder:

Use at a depth of 5 m - 100 m.
Use transducer in transom mount or thru-hull mount.
To show a consistent display of the actual bottom, set the range display of the fishfinder screen to "auto".
Enter the ship's draft value
Use a ship speed of 10 kn or less.
In some instances, bottom component indicated on the FCV-627/587 may carefully differ from its actual bottom structure. Please read the operation manual prior to utilizing this feature.

Post-Processing Gain Control

With conventional gain controls, changes are made for new echoes only when a change in the setting is applied. With the Post-Processing Gain Control, changes in the gain setting are applied to new echoes as well as all of the echoes already on the screen. Because the changes are applied to both new and existing returns, you will be able to quickly and easily find the right gain setting for your conditions.

White Line feature

Discriminate fish lying near the bottom

The top edge of the bottom echo is displayed in white to clearly show bottom structures. This feature helps to discriminate between weeds and bottom fish distincly.

Share and display information on a chart plotter*

FURUNO's TLL (Target Lat/Lon) output allows you to interface the FCV-588 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).

* Requires a chart plotter.

Transducers

All echosounders need a transducer. A transducer is a small box of metal or plastic, that is either placed outside the hull under the waterline. It transmits signals through the water and recieves the reflections from the seabed and fish. This signal is processed and is presented on the display.

FURUNO produces a number of transduceres but we can also deliver a wide range of products from or partners from AIRMAR [see website]
