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.
