Developed over years of R&D the Autotune system gives the lure the ability to perfectly center itself at the tow point delivering 3 key benefits, the ability to ensure the lure always swims straight, increasing diving depth and increased troll speed. This combination makes it unique in the world of offshore trolling minnows. A self centering tow point ensures that no matter how many fish you catch, the lure will keep swimming straight. Conventional lures with a fixed tow point cannot all be made perfectly centred to swim straight. The ability of the Autotune system to perfectly center itself every time on the bib means that the tow point can be pushed as far back on the bib as possible, meaning maximum diving depth and better action combined with higher troll speeds.
