How is the Anti-Reverse™ switch on my spinning reel used?

The Anti-Reverse switch is used to activate or de-activate a mechanism inside the reel that allows the rotor to spin in both directions when deactivated or only the retrieve direction when activated. When activated, the mechanism prevents the rotor from turning backwards during a hookset. Some anglers prefer to de-activate the Anti-Reverse to allow “back reeling” for controlling a fish or letting line play out when a fish makes a hard run.
