The Carolina rig is a popular fishing technique used primarily for bass fishing. It consists of a sliding sinker, a bead, a swivel, and a leader line with a hook at the end. This setup allows the bait to move freely, mimicking the natural movement of prey, which can attract fish more effectively. To use a Carolina rig, anglers cast the weighted line and allow it to sink to the bottom. They then retrieve it slowly, feeling for any bites. This method is effective in various water conditions and is particularly useful for fishing in deeper areas or around structures.
