The DUO Beach Walker Jumgo Grub Set lures are designed to cover all angles in flounder fishing. Unlike shads, the gentle movements and subtle vibrations produced by the grub tail visually stimulate flounder, triggering their feeding instincts and making the lure irresistible. The Jumgo Grub Set excels during slow, deliberate retrievals, offering a sticky and enticing presentation that is especially effective for low-activity flounder, making it a must-have for targeting this species.
