Savage Gear 4D Herring Shad. The 4th dimension is created with our detailed photo chrome skin print and the striking scent. The details are incredible and so lifelike that it becomes even harder for predators to resist a fully executed attack. The color design of each lure has been tested and fine-tuned to perfection. The added DNA scent level gives you an extra advantage when conditions allow. The slightly thicker front section provides better grip for the jig head and corkscrew. The soft eyes cannot fall off, and we have added a rattle slot in the tail. The mouth features a small hook guide for easy rigging. The sleek herring profile with its deadly side action, combined with the perfect photochromatic skin print and scent, makes an already incredible lure even more effective.
