The Heddon Sonar is as versatile as any lure youll find in the fishing industry. The Sonar 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. Fish deep, shallow, vertical, horizontal, fast, slow, troll, cast the Sonar does it all.
