Kalin's Google Eye Hair Jig glides while other jig combinations fall faster – and with its secret weapon: "Glass Rattle" Shockwave System. The Rattlin' Google Eye is a glass rattle thru-construction designed to call big fish in and trigger strikes! The hair used on this Google Eye jig is bucktail, as it falls slowly and is easier for fish to see. Bucktail hair fibers, unlike synthetic counterparts, are thick at one end and thinner at the other. The taper is a natural profile and produces realistic undulating action to trigger more bites in all water types.
