Shimano Thunnus CI4 Saltwater

The Shimano Thunnus Spinning Reel is a workhorse designed for the demanding needs of saltwater anglers. Engineered with Shimano’s advanced technologies and durable construction, the Thunnus is built to handle big game fish and deliver unmatched performance in any fishing situation.

The Thunnus features a robust and lightweight Hagane body construction, providing exceptional strength and rigidity. This design ensures the reel can withstand the rigors of saltwater fishing, while its ergonomic shape fits comfortably in your hands for long casting sessions. Whether you’re casting from the shore or battling offshore monsters, the Thunnus delivers the power and control you need.

Equipped with Shimano’s CoreProtect technology, the Thunnus offers superior water resistance to protect the reel’s vital components from saltwater intrusion. The CoreProtect system utilizes a series of water repellent seals and protective coatings, ensuring the reel performs flawlessly even in the harshest conditions. Fish with confidence, knowing that your Thunnus reel is built to endure the challenges of saltwater environments.

The Thunnus features a powerful drag system that delivers smooth and consistent pressure to control hard-fighting fish. The Cross Carbon Drag provides exceptional stopping power, allowing you to handle aggressive species with ease. Whether you’re battling marlin, tuna, or other trophy-sized saltwater fish, the Thunnus’ drag system will give you the confidence to conquer the challenge.

With its Cold Forged HAGANE Gear, the Thunnus ensures optimal gear durability, strength, and seamless retrieves. The precision-engineered gears are forged with Shimano’s cold-forging technology, resulting in precise gear meshing and increased power transmission. Experience the joy of effortless cranking and the confidence to handle the strongest fish in the sea.

The Thunnus features Shimano’s innovative Baitrunner system, which allows for free spooling with a secondary drag system. This feature is ideal for live bait fishing, allowing fish to take the bait without feeling the resistance of the main drag. When you’re ready to engage the main drag, simply turn the handle, and you’re ready to fight the fish. The Baitrunner system provides versatility and control for various fishing techniques.

With its Aero Wrap II line lay and Propulsion Line Management System, the Thunnus ensures smooth and accurate line management. The Aero Wrap II system provides uniform line lay on the spool, reducing friction and enabling longer and more accurate casts. The Propulsion Line Management System enhances casting performance, reduces line twist, and prevents backlashes, allowing for hassle-free fishing.

Featuring an ergonomic handle and comfortable grip, the Thunnus ensures a secure and enjoyable fishing experience. The handle’s design allows for smooth and effortless cranking, reducing fatigue during extended battles with hard-fighting fish. The reel’s overall smooth operation and comfortable handle make it a pleasure to use, no matter the fishing conditions.

Whether you’re targeting trophy fish from the shore or battling offshore giants, the Shimano Thunnus Spinning Reel is a reliable and powerful companion. Experience the thrill of saltwater fishing with a reel that’s engineered to perform at the highest level. Elevate your angling game with the Thunnus and conquer the saltwater realm with confidence.
