The Norman Lures DD22 Crankbait sets the standard for deep-diving crankbaits and is a staple for ledge fishing in the 15-18 foot range. The DD22 has been winning tournaments for decades. Being made from butyrate, the DD22 creates a dull thud that fish normally do not hear. After getting attention with the rattle and thud, the medium-wide wobble will seal the deal.
