An electrically powered indicating device for use in conjunction with a fishing rod is disclosed. The device indicates when the end of the fishing rod remote to the handle is pulled downwardly and distinguishes between a fish nibbling at the hook on the fishing line and a fish caught on the hook of the fishing line. The device comprises a protective housing, an electrical power source, such as a battery, an electrically powered indicating means such as a light emitting diode or buzzer, and a non-positive contact switch means such as a mercury tilt switch, all electrically connected in series with one another. When the device becomes tilted past a certain orientation, the non-positive switch means becomes closed, thus turning on the indicating means. When the non-positive contact switch means is closed and the device is moved abruptly or vigorously, the non-positive contact switch means becomes opened and closed intermittently. It is thereby possible to distinguish between a fish nibbling on a hook and a fish that is caught on a hook.
