Fishing float tubes are designed with angling in mind. That means a U- or V-shaped design that’s easier to maneuver and offers a higher seat, a place for fishing gear, and helpful accessories such as a stripping apron to hold fishing line. To use one, load up your tackle and rod, then place the tube in shallow water near the shore and sit on the seat. You may want to wear lightweight waders if the water is cold. Flippers will help you move through still water and paddle out deeper.
