The Northland Tackle Level-Head Inner Tube Jig is the critical missing component for anglers looking to unlock the full fish-catching potential of hollow-body tube plastics. While standard jig heads cause a tube to plummet nose-first in an unnatural vertical posture, this specialized insert distributes the weight precisely to balance the bait horizontally. When slipped inside your favorite soft plastic tube and rigged through the eyelet, it transforms a lifeless piece of plastic into a darting, spiraling, and gliding presentation that perfectly mimics a dying baitfish.
