LMAB KFI Techno Vibe (Real Perch) The KFI Techno Vibe by LMAB is a versatile vibration blade that can be customized to suit your needs. It comes with an interchangeable twin hook and a Willow Blade. The front treble hook can easily be swapped for the twin hook to reduce snagging in tricky spots, while the Willow Blade adds extra movement. In addition to its strong action, the Techno Vibe produces a distinctive sound from the rattle chamber behind the head. With two attachment points on the back, you can adjust the vibrations: when attached at the front, they are subtle, while at the back, they are more intense. This allows you to perfectly adapt the vibrations to the mood of the fish.
