The sturdy construction of the lightweight TLD reels will outperform most larger, heavier reels. The lightweight graphite frame and sideplate keeps weight down while keeping performance high. The lever drag lets you make precise adjustments while keeping your hand on the crank. Four stainless steel A-RB bearings are at least 10x more corrosion resistant than traditional stainless steel. Oversized gears and the barrel grip provide excellent fighting efficiency for large fish. All TLD reels have harness lugs and a bait clicker. The TLD50IILRSA was originally engineered to meet the needs of San Diego's long-range boats seeking hard-fighting yellowfin tuna. Its powerful drag-to-size ratio is especially suited for stand-up fishing, where maintaining freespool capability with heavy line is essential. TLD20II and 30II have the Ergonomic Power Handle; TLD50II and 50IILRSA have the Offset Ergonomic Power Grip.
