The level-wind system consists of two crossbars, which connect either side of the reel and prevent the line from getting tangled on the reel. It manages distribution of the line across the spool. The line draws from the reel, over the level wind, and onto the rod. The anti-reverse handle prevents it from rotating backward and unspooling the line. The spool, essential to most reels, holds the line, which is evenly distributed by the level wind mechanism.
The body of a spinning reel encases the spool and other moving parts.The handle of the spinning reel is the control mechanism for the release of the line from the spool for casting. The spool is set within the body and contains the fishing line. In a spinning reel, the spool moves up and down, controlling the even distribution of the line, as the level wind does for the conventional reel. The drag wire is the line-braking system for the reel. The caster applies the wire directly onto the line, slowing its release.The function of the bail is to restrict the free flow of the fishing line from the spool. When open, the line will flow without impediment. Anti-reverse, as in the baitcasting reels, provides protection against unspooling the line by reeling the handle backward.
Centerpin Fly Reel
The handle of the fly reel controls the release of the line from the spool and the retake of the line onto the spool. The foot of the reel slides into an indentation on the rod, allowing the attachment of the reel assembly. The spool sets into the reel and contains the line, which is fed through the rest of the rod. It is generally easy to remove and attach. A mechanism such as a lever usually will release the spool from the reel. It can just as easily reattach, sliding into the reel and twisting until you hear it click. There are drag systems available for fly reels. Spring and pawl systems slow the rate at which the spool can spin by forcing a triangular-shaped spool onto it via a tension spring activated by a knob or lever on the reel. The disc drag system comes in two varieties--caliper disc-drag and disc-drag. Both disc-drag systems manipulate tension on the fly line by turning a control knob on the reel. The reel holds the spool, handle and drag system. The reel attaches to the base of the rod by the foot. It can be attached in a right- or left-handed manner.
