How to use and care
Choose a flopper length that suits the fish you hunt and that matches the shaft design and the original barb. Replace a flopper as soon as it is bent or damaged, as a weakened barb can let fish slip off. Rinse the shaft and flopper in fresh water after saltwater use and check the pin and pivot area for wear. Carrying a spare set is a sensible habit on any trip.
