The Chamberlain Stacker Downrigger Release offers precision control with independently adjustable vertical and horizontal tension, giving anglers an exact setting for every trolling pass. The vertical adjustment applies added downward pressure to keep the rod loaded, eliminating slack on the strike and improving hookup speed—especially important when targeting light-biting species like walleye or coho. The magnetic-based horizontal tension system can be fine-tuned from 0 to 4.5 lbs. with just ounces of variation, making it easy to dial in specific lures, dodgers, or baits without triggering false releases. This stacker release attaches securely to steel downrigger cables and features a locking cam that holds position on the wire but automatically unlocks when it contacts the downrigger pulley. It's small-fish friendly, minimizes line slippage, and holds up under pressure thanks to stainless steel and quality plastic construction. Whether you're trolling the Great Lakes for trout or salmon or fine-tuning setups for inland species, this stacker release adds versatility and sensitivity to any trolling spread.
