Shimano's Ocea Waver Jigs feature a boat-like keel on their rear, engineered to deliver three distinct, erratic actions during dives--backsliding, wobbling and a captivating forward and backward slide. These movements all imitate the motions of wounded baitfish. These jigs come in different sizes, suitable for different depths and species. Shimano used their Scale Boost technology on select models to enhance color, while others boast luminous glow.
