The Heddon Rattling Sonar Flash is as versatile as any lure youll find in the fishing industry. The Rattling Sonar Flash features three line-tie holes, each positioned for a different fishing technique. Tie your line to the front hole for casting and fishing shallower water. Tie to the middle hole for vertical jigging. The third hole is for trolling or casting to deeper water. The Rattling Sonar Flash adds sound to this already effective vibrating blade bait.
