Furuno FCV628 5.7" Fishfinder w/RezBoost
Furuno FCV628 5.7" Fishfinder w/RezBoost — Product description
Unlock Crystal-Clear Underwater Views with RezBoost Technology
Imagine spotting schools of fish weaving through bait balls or hugging the seabed with unprecedented sharpness—all from a compact 5.7-inch color display. The Furuno FCV628 fishfinder leverages RezBoost signal processing to transform standard narrowband transducers into high-performance tools. This innovation boosts resolution and target separation by up to eight times, delivering images that reveal fine details like never before. Whether you're chasing trophy bass in shallow waters or scanning deep for snapper, RezBoost ensures every echo tells a story, helping you pinpoint prime fishing spots effortlessly.
Faster Scans for Superior Clarity
With a pulse repetition rate hitting 3,000 per minute at just 5 meters, this fishfinder refreshes screens rapidly, painting a dynamic picture of the underwater world. No more blurry clusters—individual fish stand out, making split-second decisions on your next cast or troll a breeze.
ACCU-FISH: Know Your Catch Before You Reel It In
Go beyond guessing sizes. ACCU-FISH analyzes echo strength to estimate fish from 10 to 199 cm in depths up to 100 meters, overlaying precise measurements right on the screen. Pair it with customizable fish marks—circles, squares, or symbolic icons for small (10-49 cm) and large (over 50 cm) targets—and even novice anglers gain pro-level insights. Switch to depth mode for tactical precision, turning raw sonar data into actionable intel that boosts your hook-up rate.
White Line: Separate Bottom Dwellers from Structure
Fish lurking near the bottom? The White Line feature highlights the upper edge of echoes in crisp white, distinguishing weeds, rocks, or actual fish with ease. This simple yet powerful tool prevents missed opportunities, especially in murky waters or complex bottoms where traditional sonars falter.
Bottom Discrimination: Hunt Smarter, Not Harder
Unlock the secrets of the seafloor. Connect to compatible thru-hull or transom transducers, and the FCV628 graphically identifies bottom types—rocks, sand, gravel, or mud. This at-a-glance intel guides you to fish-holding structures: rocky outcrops for walleye, sandy flats for flounder. Combine it with TLL output to share latitude, longitude, depth, temperature, size, and bottom data directly to your Furuno chart plotter, marking hotspots for future trips.
Stay Alert with Custom Alarms and Seamless Integration
Never miss a bite again. Set alarms for fish echoes in designated zones, water depth changes, temperature shifts, or specific bottom compositions—the unit beeps loudly and flashes icons to grab your attention. It's like having a vigilant deckhand. For bigger setups, TLL compatibility lets you log everything on a compatible plotter, building a database of proven fishing grounds over time.
Built Tough for Real-World Fishing
Powered by 600 watts at dual 50/200 kHz frequencies, it probes up to 1200 meters while sipping 12-24 VDC from your boat's system. The vivid color LCD thrives in sunlight, ensuring readability during peak action. Compact and rugged, it's ideal for kayaks, center consoles, or offshore rigs.

Maximize Your FCV628: Angler Tips for Peak Performance
Pair RezBoost with a quality narrowband transducer for best results—think single-element designs tuned to 50 or 200 kHz. Adjust gain and range dynamically: high gain for deep scans, auto for shallows. Use ACCU-FISH in tandem with fish marks during dawn patrols when visibility dips. For bottom bouncing, toggle White Line on to nail those subtle hooksets. Regular transducer cleaning keeps echoes pure, extending your edge on the water.
Frequently Asked Questions
What makes RezBoost technology stand out on the Furuno FCV628?
RezBoost enhances narrowband transducers, multiplying resolution and target separation by up to 8x for sharper fish and structure images compared to standard processing.
How accurate is ACCU-FISH for measuring fish size?
ACCU-FISH assesses fish from 10-199 cm in depths to 100 m by analyzing echo strength, providing reliable estimates enhanced by RezBoost for better visibility.
Can the FCV628 identify different bottom types?
Yes, with supported transducers, Bottom Discrimination displays rocks, sand, gravel, or mud graphically, helping locate fish-attracting structures.
What alarms are available on this fishfinder?
Customizable alarms trigger for fish echoes, depth, temperature, bottom type, and more, with audible alerts and on-screen icons.
Does the FCV628 work with Furuno chart plotters?
Absolutely, TLL output shares target data like position, depth, size, and bottom info for marking spots on compatible plotters.
What's the ideal power setup for the FCV628?
It runs on 12-24 VDC, making it versatile for small boats to larger vessels without needing extra power converters.
How does White Line help in fishing?
It whites out the top of bottom echoes, clearly separating fish from weeds or structure for precise bottom fishing.
The 5.7" FCV628 is a dual-frequency fish finder equipped with revolutionary new RezBoostT signal processing technology that increases resolution and improves target separation by up to 8x, utilizing a compact narrowband transducer. It offers improved clarity and resolution previously impossible with conventional narrowband transducers. A fast transmission rate of 3,000 PRR (Pulse Repetition Rate) per minute (at 5 m depth range), ensuring excellent target separation and clarity.
The FCV628 includes a White Line feature to easily and accurately 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.
The FCV628 also offers a number of unique features only found on Furuno Fish Finders. ACCU-FISH is a unique fish size analyzer based on the latest digital technology. Accu-Fish allows the FCV628 to display the actual fish size on individual fish echoes on-screen. When used concurrently with Fish Marks, Accu-Fish is a great help in identifying fish targets on the display. Alternatively, Accu-Fish can display the actual depth of the fish target instead of fish size.
Bottom Discrimination provides 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.
The FCV628 comes equipped with a number of configurable Alarm functions such as depth and fish echo alerts.
Furuno's TLL (Target Lat/Lon) output allows you to share and display information on a chart plotter. Easily interface the FCV628 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).This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
