The rotating blades create a low-pressure vortex that originates at the point of contact with the central axis (post) of the bait. As the bait moves forward the low-pressure area will move above the central axis in a speed-dependent manner due to the surrounding water pressure The Head Shot is freely rotating around the post this allows the head to be "sucked" into an upright position. Since the low-pressure area is inconsistent in nature the head will wobble from side to side adding to the appearance of a struggling baitfish. The head gives the predator a distinct target triggering a strike.
