  • Patent number: 5915941
    Abstract: A lighted slipbobber receives the fishing line along its vertical central axis to maximize stability and includes a blinking LED protectively encapsulated within the bobber body and laterally offset from the central axis. A light pipe extends from the offset LED to the top of the bobber and terminates in a lens on the vertical central axis. The LED is energized by an improved capacitive energy storage circuit within the bobber, and the circuit significantly increases operating time between recharging of the circuit. No batteries are carried by the bobber.
