Discover the reliability of the Furuno CA28F-8 rubber-coated transducer, engineered for serious anglers and commercial mariners chasing big game in deep waters. With its robust 1kW power output and precise 28kHz frequency, this transducer delivers exceptional bottom tracking and fish-holding structure detection down to extreme depths, making it a go-to choice for offshore adventures.

Superior Performance for Deep-Water Detection

The CA28F-8 shines in challenging marine environments thanks to its optimized 31x34-degree beam angle. This asymmetrical design provides wider fore-to-aft coverage, ideal for boats underway, helping you spot schools of tuna, swordfish, or wrecks with clarity. At 28kHz, it punches through thermoclines and sediments better than higher-frequency options, ensuring you never miss the mark on structure or bait balls.

Paired with Furuno's high-end sounders, it unlocks crystal-clear sonar images, reducing clutter from sea noise and enhancing target separation. Whether you're trolling lures or dropping jigs, this transducer's power handles the demands of professional-grade fishing without compromising on accuracy.

Flexible Installation Options

Designed for versatility, the rubber-coated housing mounts securely to the hull chest or inside a tank, minimizing drag and protecting against impacts from debris or docking. Its 13.2-pound weight offers stability on larger vessels, while the 15-meter cable gives ample reach for clean routing to your display unit. Note that no plug is included, allowing custom wiring to match your setup—perfect for DIY installs or upgrades.

Installation is straightforward: secure it parallel to the waterline for optimal beam projection, and seal thoroughly to prevent water intrusion. This flush-mount style thrives on planing hulls, delivering consistent performance from trolling speeds up to 20 knots.

Built to Withstand Harsh Conditions

The durable rubber coating isn't just for show—it's a shield against corrosion, UV exposure, and biofouling, extending service life in saltwater. This transducer laughs off rough seas, maintaining peak performance season after season. At 13.2 lbs, it's hefty enough for secure mounting yet manageable during setup.

Regular maintenance keeps it humming: rinse with fresh water after every trip, inspect the cable for wear, and check the face for growth. Avoid high-pressure washes directly on the elements to preserve sensitivity.

Why Anglers Trust This Transducer

Beyond specs, the CA28F-8 stands out for its real-world reliability. Captains report fewer false readings in heavy cover, sharper arches on fast-moving pelagics, and reliable depth readings over rugged bottoms. It's not flashy, but its no-nonsense design has earned a reputation among charter fleets for delivering results when it counts.

Upgrade your sonar game and fish smarter, not harder, with a transducer proven in the trenches of big-water pursuits.
