  • Patent number: 11622549
    Abstract: The magnetic casting brake hereof provides little magnetic brake force at the start of a cast by providing magnets on a curved cam able to rotate with the spool and move closer to the spool to achieve sufficient brake force to avoid a backlash. When the cast is finished, and one begins to retrieve the bait, the magnets rotate back to a minimum position so that retrieval will be lighter, and the feel of the lure will be increased. The casting brake will also include an off position to provide free spool.

  • Patent number: 8602343
    Abstract: A drag/free spool controller incorporated into a fishing reel that has a signal generator mechanically attached to the reel. When the spool spins the signal generator produces a voltage signal, and after a pre-determined number of rotations, the generated signal is compared to a pre-determined value to determine if the spooling corresponds to a fish strike. When the generated voltage signal exceeds the pre-determined value, indicating a fish strike, a solenoid attached to the reel is actuated to disengage the drag mechanism, placing the reel into a free spool position. This action allows the fish to run with the bait while the angler repositions himself to manually engage the drag to set the hook. If after a pre-determined interval the angler fails to manually engage the drag, the solenoid will do so automatically.
