[header] How to cast [title] Reel in the line until your bait or lure is six to 12 inches (15 to 30 centimeters) from the rod tip. [step] If you have a sinker or bobber attached to the line, it should be six to 12 inches from the rod tip instead. [title] Grip the rod behind the reel with your thumb resting over the button at the back of the reel. <sep> (A) [step] Most lures have a " c " grip, so you can feel down either the hook and lure, or on the rod itself. [title] Use your thumb at the bottom of the reel. (B) [step] The button is a " gear " shaped piece of metal at the bottom that holds your line and reel. The button itself is kept in place on the reel. (C) [step] Most spincasting rods have a recessed seat and a trigger-like projection for you to wrap your index finger around. [substeps] Most fishermen cast spincasting gear with the same hand they reel the line in with. (D) [step] Bring this hand around the outside of the reel flap and behind the belly button. You will now be holding the rod in that position while bait is cast, or fillet, on the rod tip.
