How does the conical drag work on a fly reel?

Conical drag on a fly reel operates by utilizing a conical-shaped surface that creates friction against a corresponding conical component when the drag is engaged. As the fish pulls line, the pressure applied increases the contact area between the surfaces, enhancing resistance and controlling the line's release. This design allows for a smoother, more consistent drag, minimizing sudden surges that can lead to line breakage. Overall, conical drag systems provide a reliable and adjustable means to manage tension during a fight with a fish.
