The Mack's Shuttle Hawk Downrigger Stacker streamlines multi-rod trolling setups, letting anglers target salmon, trout, and lake species at multiple depths with precision. This innovative stacking system attaches directly to your downrigger cable, carrying your release and lure down to the desired depth before automatically returning to the surface when tripped. A weighted internal body enables the Shuttle Hawk to dive or rise smoothly, while the three-bump slotted channel securely grips the cable during deployment. The ultra-release screw lets you fine-tune line tension for any trolling speed or species. Each kit includes two ultra releases and one downrigger stop for easy rigging and dependable performance.Downrigger stacking system for trolling multiple depthsWeighted body dives and returns smoothly on releaseAdjustable ultra-release screw for precise line tensionIncludes two ultra releases and one downrigger stop Made in the USA
