How Square Bill Crankbaits Work for Bass

Square bill crankbaits have a hard, square lip that deflects off cover like stumps and rocks, triggering reaction strikes from bass. When you reel them in, the lip makes them wobble and roll violently, which mimics a fleeing crawdad. The short bill keeps the bait running shallow, usually 2-6 feet, so you can bump it through timber and brush without hanging up. Pausing it lets it float up, just like a bass is about to eat it.
