Abstract
A drag control for a spinning reel includes a disc that rotates with the main shaft. A primary drag plunger is moved against one side of the disc to establish the preset drag. The secondary drag plunger directly opposing the primary plunger is mounted on a cam follower, and a hand-operated cam moves the follower selectively toward or away from the disc. The cam is tapered from side to side so that a different range of movement will be imparted to the cam follower, depending upon the circumference of that portion of the cam engaged by the cam follower.
