Engineered to dominate both fresh and saltwater environments, the Shimano Tranx 300 B is the ultimate low-profile baitcasting reel built for serious anglers who demand strength, precision, and performance. A complete redesign of Shimano’s proven “workhorse” series, the Tranx 300 B delivers unmatched durability and power with advanced technology packed into a compact frame.
Constructed with CoreSolid and HAGANE Body technologies, the reel integrates the B-side plate, level guard, and frame into one ultra-rigid aluminum structure. This seamless design eliminates flex, resulting in exceptional cranking power, sensitivity, and long-term durability.
The SVS Infinity MD Tune braking system provides effortless, on-the-fly casting control through an external adjustment dial, allowing anglers to fine-tune performance for any lure weight or wind condition. Combined with X-Ship technology, which minimizes friction between the spool shaft and gear, the Tranx 300 B offers buttery-smooth operation and extended gear life under heavy loads.
From working big swimbaits to battling trophy saltwater species, the Shimano Tranx 300 B stands as the definition of versatility, power, and precision engineering—redefining what a baitcasting reel can do.
