SWING Spinner baits are very effective in all conditions. They can be fished by buzzing across the surface, by a steady retrieve, and by slow rolling off of ledges and other underwater structure. Spinner baits have one to two blades which rotate during bait retrieval. The blades cause turbulence and vibration which attract fish and enhance the fish’s ability to find the bait in stained water. For this reason spinner baits are very effective at night.
