The hard plastic tail of the Waggerbait™ swim jig is weighted at the back end. This is the area of greatest lateral speed during the pendulation of the tail when being retrieved. By weighting the tail there it maximizes the production of kinetic energy. The tail rides directly on the round of the hook shank. It is this co-operative engagement between the hook and the rigid tail that results in the transfer of energy to the jig portion of the bait. The energy transfer results in the creation of noise by two methods, the direct contact of the stainless steel eye loop of the tail on the wire of the hook shank ( like plucking a guitar string ) and the hesitation in the forward movement of the jig which activates the rattle attached to the hook shank just behind the skirt. This results in a unique sound and vibration pattern that triggers big bass
