The original action-adjustable lure, the Heddon Sonar Flash has 3 line-tie holes allowing for adjustment of the lure's running depth and action.
The front hole is for shallow running and high vibration. The rear hole produces deep running and a wide, slower, wobbling action. The center hole is perfect for jigging, a technique especially effective for ice fishing.
Whether cast, trolled or jigged, the Sonar series has the perfect vibrating action to entice most freshwater species into rod-busting strikes.
