The Autotune design provides for 2 key features– maximum diving depth, and the ability to ensure the lure always swims straight. The DTX minnow with Autotune will always swim straight, first time and every time, no matter how many fish you catch.
The other key feature of the Autotune system is the amazing diving depth that can be achieved. The ability of the system to perfectly centre itself every time on the bib means that the towpoint can be designed to be as far back on the bib as possible, effectively just forwards of the point where the lure becomes unstable and won’t swim. However, having the towpoint as close to this “point of not swimming” is what achieves maximum diving depth, but it can only be done with a perfectly centred towpoint. Traditional fixed eyelet trolling lures are unable to position the towpoint this far back on the bib and have to allow room for error in the manufacturing process.
In addition to the Autotune technology, the concealed Hydrospeed belly eyelet allows faster trolling speeds with single hooks, and ensure the lure is balanced with single hooks, so the DTX minnow just keeps swimming straight and true. The additional belly eyelet in front of the Hydrospeed eyelet is designed to be able to fit an assist hook onto when targeting large tuna and marlin.
