   An electronic ice fishing system provides an enhanced alert to a fisherman of a fish strike. The electronic ice fishing system comprises an electric circuit with a radio transmitter and a magnetic reed switch encased in a weatherproof housing. The housing is attached to the frame of any of a number of conventional type fishing tipups. A ferrous plate is bonded to the housing proximate the magnetic reed switch inside. A magnet is placed on the ferrous plate, and the magnet actuates the magnetic reed switch to an open state. The magnet is tied with a cord to the flag alert of the tipup. When a fish strikes, the flag alert trips and pulls the magnet from the plate. As a result, the magnetic reed switch closes, and the radio transmitter is energized to signal a pager carried by the fisherman, who can be at a substantial distance and out of sight of his tipup. In a modified embodiment, the magnet and the plate are inverted. The magnet is captured inside the housing, and the plate is inserted into an external recess in the housing. The external recess is located between the magnet and the magnetic reed switch. When the plate is pulled from the housing recess by the tipup strike alert, the magnetic reed switch closes to energize the radio transmitter.

   A fishing device comprises a rod formed in two rod portions connectable at a center position by a coil spring attached to both of the rod portions. The coil spring is wrapped around the upper portion and is releasably attached to a cap on the lower portion which is of a larger diameter. A battery, speaker and fishing line are mounted on the lower portion. A hook is mounted on the upper portion at a position spaced from the upper end. A simple spring steel arm is fastened to one side of the lower portion and projects out beyond the end of the lower portion to position alongside the coil spring. With the fishing line attached to the hook on the upper portion, when the fishing line is pulled it distorts the upper portion and thus bends the spring into contact with the spring arm and this causes the completion of a circuit connecting the battery to the speaker. A spike at the lower end of the lower portion can be inserted into the ice adjacent an ice fishing hole. The spacing of the hook on the upper portion from its end enables the end to contact the ice on the side of the hole opposite the spike so that the unit cannot be pulled through the hole and lost.

   The present invention is a device for detecting the movement of a fish on a fishing line, which comes in two parts: a detecting and transmitting device ( 10 ) which can be attached to a fishing rod, and a receiving device ( 10 ) which also functions as a storage box. Movement of the fishing line is detected using a piezoelectric crystal or other sensing device. There is a rotatable control ( 34 ) for adjusting the sensitivity of the device. The sensing device produces an electric signal which is processed by electronic circuits, encoded, and transmitted as radio waves. The radio waves are received by the receiving device, converted back into an electric signal and decoded. When an appropriate signal is received, either a buzzer ( 64 ) or a vibrator ( 66 ) is activated to alert the user that a fish is on the line. A toggle switch ( 58 ) enables the user to choose whether the buzzer or the vibrator will be activated.

   A fishing tip-up device is provided. A magnet holds a signaling device in a non-activated state. When an electronically operated sensor device senses movement of a fishing reel, a signal is sent to the magnet which causes the magnet to release the signaling device to indicate the occurrence of a possible fish strike. An annunciator turns on and off as a result of the sensing device sensing the rotation of the reel. The electrical circuit is activated when a fishing rod is properly positioned within a base frame of the fishing tip-up device. The electrical circuit is deactivated when the fishing rod is properly placed within the base frame for storage and transportation. The fishing tip-up can be manipulated into a single compact unit which is convenient for storage and transportation. A fishing reel is provided which creates drag in the unreeling of the fishing line when a fish takes off with the bait, thereby inhibiting the fish from unreeling the entire line. 
   While these fish strike indicators may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.

Shown is an alternate device of the present invention  10 , having a battery box  18  that is an integral part of the tip-up base  20 . The flashing light sequence and RF transmissions are controlled by the electronic circuitry contained on the circuit board  36 . When activated by the tilt-sensitive switch, the circuitry creates a flashing sequence. While the lamp  34  is flashing, the RF circuitry sends periodic transmissions that can be received by the receiver. The sequence is repeated until the tilt-sensitive switch is moved to a reset position or power is disabled by the user. Other previously disclosed elements are also shown. 
     FIG. 12  is a circuit block diagram of the alternate device of the present invention. Shown is the circuitry of the alternate device of the present invention. The circuit board contains all necessary circuitry to control the flashing sequence of the lamp  34  and the RF transmissions  50 . 
     FIG. 13  is a circuit block diagram of the alternate device of the present invention when the RF transmitter function is not included. Shown is the circuitry of the alternate device of the present invention. When the RF transmitter functionally is not included, the circuit board controls the flashing sequence of the lamp  34 . Once activated, the circuitry creates a flashing sequence by turning on the bulb  34  for a period of time and then off for a period of time. The sequence repeats until disabled. 
     FIG. 14  is a detailed view of the present invention. Shown is the present invention being a tip-up light and RF transmitter assembly  12  having a bulb  34  that is bright and replaceable by means of a bulb socket mounted on the circuit board  36 . The bulb control head  12  contains a tilt or mercury switch or rolling ball style switch which activates the electronic circuitry when the flag is tripped. Once activated by the tilt-sensitive switch, the circuitry creates a flashing sequence by turning on the bulb  34  for a period of time, then off for a period of time. While the lamp  34  is flashing the RF circuitry sends periodic transmissions that can be received by the receiver. This sequence is repeated until either the tilt-sensitive switch is moved to such a position as to disable the circuitry or power is removed. Other previously disclosed elements are also shown.
