Jackall SpeedVib, 42mm, 7g

High contrast reaction bait
The lure is designed to start action as soon as line tension is applied, allowing it to appeal to fish as much as possible within a short travel distance.
Two types of falls
If you apply a little line tension while it falls, it will curve fall, but if you lift it until it stops completely and then release the line tension all at once, it will slide irregularly while falling. You can aim for a reaction bite with this irregular action that makes it hard to predict where the lure will go.
The action power that fills the gap between the extremely finesse action of the TN38 and the strong action of metal vibrations like the Knockin' Joe expands the range of tactics you can use.
