A drop shot rig is another fishing technique that uses a weighted soft plastic lure rigged with a bullet weight and snaps swivel above the hook. The sinker rests on the bottom of the body of water while the bait hangs just off the bottom in front of the fish. The main difference between a drop shot rig and a Carolina rig is that the sinker on a drop shot rig is usually attached to the line above the hook, while it is attached below the hook on a Carolina rig.
