Shimano Tranx 300B Baitcasting Reel
Shimano’s redesign of a low-profile baitcasting reel renowned for its smooth, powerful performance and unmatched durability, the Tranx 300 B builds on the series’ “workhorse” reputation with premium technology enhancements designed to tackle both fresh and saltwater environments. Crafted with precise intention, the Tranx 300 B features Shimano’s CoreSolid and HAGANE Body technologies, which integrate the B-side plate, level guard, and reel frame into a single, ultra-rigid aluminum piece. This seamless construction ensures an incredibly flex-free platform, allowing for exceptional rigidity and sensitivity that directly translates angler action into cranking power.
The Tranx 300 B is equipped with Shimano’s SVS Infinity MD Tune braking system, offering easy, on-the-fly adjustments through an external dial. Whether casting heavy or light lures, this system allows anglers to fine-tune brake settings for maximum control and accuracy. Built to leverage large fish, the Tranx 300 B incorporates X-Ship technology, significantly reducing friction between the spool shaft and gear. This innovation dramatically enhances gear durability, ensuring the reel is ready for any challenge. Packed with features that elevate casting and cranking performance, the Shimano Tranx 300 B redefines baitcasting utility for the angler.
