A bait-casting reel sits on top of the rod. It is different from spin-casting reels in that it features a line spool that is horizontal to the rod.
This type of reel requires more skill to use because of the way the line comes off the reel.
To cast, begin by holding the rod about waist level, grasping it so that the reel is above the rod, and your thumb falls naturally on the bottom of the spool. The bait or lure should be hanging 8 to 10 inches below the tip of the rod.
Push the button to put the reel in free spool while holding your thumb against the spool to prevent it from unwinding. Next, pull the rod back so the tip sweeps over your dominant shoulder, and then bring it forward swiftly, pointing the rod tip at your target.
As the rod comes forward over your shoulder let your thumb off the spool so the lure can pull line from the reel. Place your thumb back down on the spool as the lure splashes into the water. Reel once or twice to engage the anti-reverse and you're ready to fish.
