Throughout history, anglers have made numerous advancements in the design and construction of fishing reels. Fishing reels are designed to cast line smoothly and accurately, while providing superior usability and control. However, there are several factors that anglers should consider before buying a reel. They can be categorized into two groups: spinning and conventional.

The spinning reel is the most common type of reel used by anglers today. It is usually used for casting larger lures and heavier test lines. However, spinning reels can also be used with smaller baits. The main difference between a spinning reel and a conventional reel is the spool's spinning speed. A spinning reel's spool usually spins at a slower speed than line is released. This can lead to the line tangle called a "bird's nest" and can be difficult to untangle. A conventional reel's spool usually spins faster than the line is released. The spool is typically mounted above or below the rod handle.

A spinning reel works well for many types of fish. However, it can be difficult to learn to cast it properly. The main thing to remember when casting a spinning reel is to hold the line loop down with your index finger and whip the rod forward. This will prevent the line from flying off the spool.

Baitcasting reels are similar to spinning reels, but they are designed to produce a high level of pulling power. The advantage to a baitcasting reel is that you can stop the line at any time and still be able to control the reel. This is useful for saltwater fishing, catfish, and largemouth fish. It also allows you to feel the line as it goes out. A baitcasting reel is generally the most powerful type of fishing reel available.

Baitcasting reels tend to have backlash problems, which can snare loops of line in narrow spaces between the spool and reel chassis. This can be difficult to untangle and is usually called a "bird's nest." Reel manufacturers have been working to develop anti-backlash features. They have also created new drag settings.
