The D-TRAK super deep diving and long casting crankbait features the famous Patented Autotune System. Autotune ensures every lure always tracks straight and more importantly allows the D-TRAK to reach incredible depths. Autotune guarantees you cannot over crank this bait. Reel as fast as humanly possible and D-TRAK will respond by digging deeper! D-TRAKs Autotune guarantees anglers a competitive advantage over all other deep cranks. The extra body action offered by the Autotune System means that the bait can beworked super slow and still reach incredible depths, or it can be power fished hard and fast when searching. This unique Autotune System makes the D-TRAK the only deep diving crankbait that can be slow rolled in Hartwell or burned in Lake Mead.
