Ensure every strike counts when bringing a giant fish to the boat. Available at Tightlines Tackle, this 4.5" Bronze Harpoon Dart is a heavy-duty, commercial-grade tuna dart poured from high-density New England marine bronze. Engineered specifically for serious offshore harpooners and commercial Bluefin crews, its 4.5-inch streamlined profile provides the ideal balance of penetration speed and structural weight—driving deep through tough hide, meat, and bone before toggling flat to lock in place.

Machined with a clean, precise internal socket designed to seat smoothly onto standard 3/8-inch harpoon pikes, this unrigged dart allows mates and captains to rig their terminal setups to custom specifications—whether using heavy vinyl-coated stainless steel cable or 4,000 lb AmSteel-Blue Dyneema braid. Poured with extra material around the line eyelet to prevent wearing or shearing under extreme tension, this 4.5" bronze dart is built to withstand massive strain from giant Bluefin Tuna, Swordfish, and sharks.
