The Strike King Pro-Model XD Silent Crankbait series includes the 5XD & 6XD. These crankbaits are designed with a unique curved bill and are balanced to cause a steep dive angle to enable these baits to dive faster and deeper than other crankbaits in this category. The bill design also enables the lure to track well when in contact with the bottom. The longer you can cast the deeper a crankbait can go and these lures cast far!
