The Heddon Sonar Blade Bait is the original action-adjustable lure. The three line-tie holes allow adjustment of the lure's running depth and action.

The center hole is perfect for jigging, a technique especially effective for ice fishing. Original action-adjustable lureThree line-ties allow you to choose action
