The Autotune Bib system allows the lure to self tune, and adjust to changes in the lure shape from fish hitting it, or other problems that often cause lures to need tuning in order to swim straight. The flexible and moveable  towpoint means that the lure is always trolled from the perfect centre line of the lure, meaning perfect balance and straight swimming always. There is no longer a need to be tweaking the tow point and bending eyelets sideways and testing the lure to make it swim, just deploy and start catching fish!
