Abstract: A protective head for bait fish that enables rapid adjustment of line position and bait shape without restringing the line or replacing hooks. The line runs through a plug that fits into any of several holes in the front of the bait protector. Using different holes changes the spin of the bait. To change holes, the plug is removed from its hole by sliding it along the line, the line is shifted to another hole along slots that connect the holes, and the plug is reinserted into the new hole; no rerigging is needed. Embodiments of the invention may also use a tuning wire that is inserted through the cup face and into the bait, and that can be bent to shape the bait as desired. The bait protector cup depth exceeds that of other protectors, eliminating the need for precise cuts to fit bait into the cup.
