An underspin reel (also known as a triggerspin reel) functions similar to a spincast reel, and hangs on the lower side of a spinning rod. You can use an underspin reel to cast through a trigger mechanism. These reels come pre-spooled and work for most types of freshwater fish, though they work best with light tackle. At Sportsman's Warehouse, you can find an underspin combo that perfectly pairs your rod and reel for your unique purposes.
