Abstract
A casting reel (10) has a reel housing (22). A reel spool shaft (14) is rotatably mounted in the reel housing. A magnetic disc (12) is connected to rotate with the shaft (14). An electrical coil (20) produces an output signal in response to movement of the disk (12). A control circuit (28) is connected to receive the output signal from the electrical coil (20). The control circuit (28) has a thyristor (52) which produces a drag signal that varies based on the output signal from the electrical coil. The electrical coil and magnetic disk provide a variable drag on the reel spool shaft (14). The variable drag changes based on the drag signal from the thyristor (52).
