Curious bass, by their very nature, exhibit strong and aggressive reactions to objects they cannot fully discern. The UMA Death Roll generates intense water vibrations and screw sounds from its constantly forward and backward rotating body, effective from dead slow to ultra-fast retrieves. Although it appears to move in a straight line like an I-shaped lure, the constantly rotating body and turbulent water flow create a mesmerizing effect that makes it difficult for bass to identify the lures true nature.

From the initial prototype stage, the Death Roll has mysteriously captivated big bass. The UMA Death Roll is now completed as a technical joint big bait, not just a lure to be retrieved straight. It features a complex 2-joint, 3-body structure, enabling not only straight retrieves but also twitching head-shake actions and kill actions during sudden stops.
