They have a tendency to backlash or snarl when the spool spins faster than line is paying out, especially when casting into the wind. To set it for each lure, hold the rod perpendicular to your body, disengage the spool and loosen the tension just until the lure starts to drop, then tighten slightly. To cast, disengage the spool and hold your thumb on the spool. Release thumb pressure on the spool when you want the lure to move forward. It is crucial to learn to control spool revolution speed with your thumb.
Line is wound onto the spool as a bail rotates around it.
Spinning reels can handle practically any size line, but they are preferred for lightweight lures and line lighter than 10-pound test. They also perform better than baitcasting reels for casting into the wind. A disadvantage of spinning reels is that they eventually twist the line, creating loops, knots and tangles. When these occur, it is best to replace the line. To help prevent line memory and tangles, drop your spool in a glass of water the night before you go fishing and let it soak overnight.
