The Freedom Tackle Tube Jig Head is a revolutionary design that we nicknamed The Whale because of its unique body shape. The Whale head design places more of its zinc-body, below the hook to keep the hook positioned mid-body. This design keeps the hook accessible and ensure there is less plastic to improve penetration of the super sharp Gamakatsu hook with vertical, 90-degree eye. The flat bottom of the head keeps the jig hook upright and reduces rolling when dragging on virtually any bottom structure. This design will keep you from losing your bait to bottom debris like rocks and wood. Each tube jig is also embossed with the weight of the jig to take all the guess work out of rigging up and get the perfect ratio of weight to depth dialed in.
