  • Patent number: 5720441
    Abstract: An attachment for controlling the distance of a casting lure attached to an end of a fishing line, includes a pressure pad extending from and connected to at least a portion of a distal lip of a spinning reel spool. During casting of the lure and line, the line on each revolution of the reel passes along an outer surface of the pressure pad, such that the fisherman can press his casting finger on the line against the pressure pad with varying intermittent finger pressure to increase and decrease drag on the line as the line spools off the spool and passes over the pressure pad. This assures greater casting accuracy so that the lure will land at a desired landing spot.
