Shimano Tyrnos Saltwater Trolling Reels feature an open top crossbar design and Shimano's stainless steel A-RB anti-rust bearings. Other key features designed primarily for trolling are a ratcheting lever drag to eliminate any lever movement caused by boat vibration, and a loud clicker with enough tension to hold large baits. Additional features include over sized gears for power while maintaining a high-speed 5.0:1 gear ratio, and an extra long handle shank with an over sized ergonomic rubber power grip. Shimano Tyrnos reels are constructed with diecast aluminum frames and graphite sideplates to reduce weight while maintaining strength and durability.
