The Zerek Colossal Ruby is a larger version of the Giant Ruby, designed to reach greater depths, with a more imposing profile that attracts the attention of larger fish. The lure is made with a 100% ABS plastic body, a reinforced lip and a mass transfer system for better casting performance. An internal rattle enhances the appeal of this lure. The Colossal Ruby is the lure for the very biggest pike, zander and catfish when trolling deep from the boat. Available in multiple colors.
