  • Patent number: 7047687
    Abstract: An inductive device for fishing. The device includes an inductive circuit board, an inductive coil, an inductive shaft and a spring. The device includes of a lighting circuit board, a plurality of LEDs and a pedestal. In the process of sea fishing, since the float base is designed with a flat bottom, it is maintained at a fixed place to indicate where the fish hook is without being driven back to the shore by waves. The inductive shaft while being pulled down by a caught fish, will leave the induced range of inductive coil, at this moment, and the central LEDs will emit red light and the out-border blue LEDs will continue to light. If there is no catch of fish on the fish hook, the central LEDs will not emit red light, but the out-border LEDs will continue to emit blue light.
