The Daiwa Exist comes in four different sizes: 2000, 2500, 3000, and 4000. When choosing the best size for your needs, consider the type of fish you are targeting and the size of your line. For instance, if you are targeting smaller bass a 2000 or 2500 size reel might be the best option. However, if you are targeting larger bass or saltwater species a 3000 or 4000 size reel might be more suitable.
