The Heddon Sonar is the original action-adjustable lure. The three line-tie holes allow adjustment of the lure's running depth and action. The front hole, 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. We stock the Sonar Series in two styles, the first is a Ľoz. lure with a flash finish which enhances the ability of this proven lure to catch more fish. On the larger ˝oz. style, by encasing a one-eighth inch steel ball between a brass eye chamber and then coating the head with a skin like material, Heddon has created the noisiest, wildly-vibrating blade lure ever. Both styles offer extra-strong, extra-sharp hooks, bright, fish attracting colors and a durable finish. Heddon Sonar Flash Blade Lure $3.89
