Abstract
An elastic bladder that is filled with water. The water adds weight to the line for casting, allowing a lure to be cast farther. The bladder has an arrangement of tubes that are inserted into each other. One long rigid tube has a folding hinge at the base. A leader is secured to the bladder with a bridle. The remainder of the leader can be coiled and attached in the “v” of a lower valve that retains the water in the bladder. This coiling allows the bladder to be positioned far above the hook, allowing the hook to be placed deeper than when using an ordinary float. After casting, the hinge is released, and the bladder empties, becoming a float.
