At a Glance: Spinning Reels
Spinning reels, also referred to as "fixed-spool" reels, are generally mounted below the rod, on the reel seat. These reels do not contain a rotating spool, so the backlash from the line is minimal. The lack of a rotating spool also allows the reel to handle extremely lightweight baits and lures. The design of a spinning reel does cause line to twist and turn as it is cast and reeled in, so the best way to avoid issues is to use a supple line.
The top brands of spinning reels at FishUSA include Daiwa, Mitchell, Okuma, Pflueger and Shimano.
