Precise Design – Xtreme Action! Inside the Precision Xtreme Pencil’s durable and through-wired plastic body is an internal weight system that makes the lure one of the best-casting baits in its category. The internal weight doubles as the Dual Frequency Knocker: as the weight slides along the internal railing, it hits a durability-increasing plastic pillar and a stainless-steel weight in turns. This results in a sequence of high and low pitch, attracting fish from near and far! The extremely detailed Precision Xtreme Pencil features printed scales, a new 3D holographic eye, and comes in 12 fish-catching freshwater colors.
