Adjustable force drag brake device for a fishing reel
 A braking device for the spool of a fishing rod is disclosed which contains two separate braking adjustments. The first braking adjustment adjusts the coarse breaking force. The second braking adjustment adjusts a finer braking force. The embodiment discribed uses two springs to bias braking boards to friction boards, the two springs being adjustable separately. The first spring is adjustable by varying the linear displacement of an adjusting cylinder which is threaded into a portion of the fishing spool apparatus. A second adjusting mechanism uses a cam with a varying radius pending on the location of the cam. This varying radius is biased against a leaf spring, thus varying the displacement of the one end of the lead spring depending on the location of the variable cam.
