LMAB KFI Xtra Vibe (Gold) The KFI Xtra Vibe is a handy accessory that allows you to quickly and easily convert your Multi Vibe into a spinnerbait. This innovative spinnerbait arm comes with a double blade in Willow shape and thus provides a completely new bait presentation. With a few simple steps, the Xtra Vibe can be quickly mounted in place of the normal blade. A silicone tube makes it possible to securely fix the connecting joint. This change ensures that the lure generates completely different vibrations under water, which are particularly enticing for predatory fish.
