The Wise Man's Downrigger
More effective for high speed deep trolling than a downrigger. Attaches to the cleat and runs off its own independent line. The line from the rod separates from the planer allowing the angler to fight the fish freely. Unlike the conventional downrigger, you dont have to retrieve it each time you hook a fish. Planer line is 300 Lbs test , 36 feet.
An inexpensive alternative to a downrigger, the high speed planer allows you to run lures deeper. The rope is secured to a cleat, the planer is set, and your line is connected via a #64 rubber band that breaks when the fish strikes.
