The Berkley PowerBait® Hollow Craw imitates a realistic crayfish and has a floating body and claws. This means that when fishing on a Texas Rig, Carolina Rig, Cheb Rig, Ned Rig or Jighead the Craw will stand up on the bottom, just like a real crayfish does when defending itself. Absolutely impossible to resist for any big perch, zander or bass.
