The Heddon One-Knocker Spook takes Heddon's proven "spook" design one step further by adding a single tungsten rattle contained inside a specially designed sound chamber. The sound chamber actually intensifies the distinctive 'thump' that one-knockers produce, generating added attention from bass lurking below. The Heddon One-Knocker Spook also walks-the-dog even easier thanks to position of the new rattle chamber in the lure's body. Available in a variety of bass attracting colors, the Heddon One-Knocker Spook is a new take on a legendary design and still a great choice when the topwater bite is on.HeddonLengthWeightClassOne-Knocker Spook4-1/2"3/4ozSurfaceUpgrade Your Treble Hooks!
