A Carolina Rig is a popular fishing rig that consists of a sliding sinker, bead, swivel, leader line, and hook. It's designed to keep the bait close to the bottom while still allowing it to move naturally. The sliding sinker allows the bait to move freely, while the bead protects the knot from damage. The swivel helps prevent line twist, and the leader line and hook are used to attach the bait. This rig is great for catching bottom-dwelling fish like bass and catfish.
