The XZone Mega Swammer is designed with unique rib design and a three-dimensional paddle tail with a keel shaped body that creates a side to side rolling action and enticing vibration. The 5.5in mega swammer is infused with XZone scent formula with Superfine Salt that makes fish hold longer and increases hook up ratios. For best hook up ratio, fish it with hook sizes 5/0 ? 7/0. Ideal for fishing through vegetation, structures, and even deep rocky ledges. They can be fished weightless as well. This bait is the ultimate fish catching swimbait for bass anglers.
