Livingston Lures feature Electronic Baitfish Sound Technology, (EBS), which is embedded on a smart chip in the internal sound chamber of each lure. This EBS Technology produces natural biological sounds mimicking baitfish that bass, walleye, pike, redfish, striper, perch and all predatory fish feed on. Natural baitfish sounds call fish from beyond their sight, including in dark or dirty water. Once fish are called and are in sight range, the sounds trigger instinctual survival strikes. The technology is activated when the lure is submerged in water & automatically turns off when out of the water and completely dry. The PRO SIZZLE calls up fish producing explosive surface blow ups and strikes like no other lure. With one twitch of the rod, this bait is designed to easily let any angler "Walk-the-Dog" like a pro. Add a little pause to the twitch and let the EBS biological sounds drive the prey crazy. This lure also features an Illumination in the tail.
