Shimano Thunnus CI4 Saltwater Spinning Reels are lightweight and have the power to stop big fish. Thunnus takes a page from Shimano's Bicycle Division using Carbon materials in high impact situations. The Thunnus CI4 is a response to all the anglers out there who wanted ease of use and functionality in a lighter weight reel. The Thunnus CI4 weighs up to 7 ounces lighter than the original Thunnus reels without sacrificing any power. Due to new drag systems for the main drag and the baitrunner drag, the Thunnus CI4 is the most efficient live bait spinning reel on the market with unmatched adjustability for fishing any bait in any condition as well as the smooth stopping power that this generation of Thunnus will be known for.
Versatility is the hallmark of Thunnus CI4 reels. Casting plugs, drifting live bait, slow trolling and more the Thunnus CI4 can do it all. This reel features a baitrunner feature which when engaged allows fish to run with the bait freely, without drag. When you want to set the hook flip down the switch and the main drag takes over.
