River 2 Sea Sea Rock A metal jig designed with a 40 Ú 60 fashion with most of the weight towards the head of the jig. This head heavy, concave body design gives Sea Rock a wider wobble that is good for a slower, more erratic retrieve at any depth. Heavy and compact, with a lumo underside glowing even in the dark, the Sea Rock will take you deep, where the big ones lay waiting. ThruÐwire construction insures the lures wonÕt pull apart regardless how brutal the battle is.
