Shimano Thunnus CI4 Baitrunner Spinning Reels

The Shimano Thunnus CI4 Baitrunner Spinning Reels combine lightweight performance with the stopping power needed to handle powerful inshore and offshore gamefish. Built using Shimano’s advanced CI4 carbon construction, the Thunnus CI4 significantly reduces overall reel weight while maintaining exceptional rigidity and strength under heavy loads. Compared to previous generations, these reels are dramatically lighter without sacrificing durability, making them ideal for anglers fishing live baits for species such as striped bass, tarpon, snook, sailfish, and tuna.

Designed around Shimano’s proven Baitrunner system, the Thunnus CI4 offers unmatched live bait control and adjustability in changing conditions. Separate main drag and Baitrunner drag systems allow precise tension adjustments for free-swimming live baits while still delivering smooth, powerful drag pressure when the fight begins. Combining lightweight carbon technology with refined drag performance and dependable saltwater durability, the Thunnus CI4 remains one of the most versatile and effective live bait spinning reels available.
