Taking It to the Field: The Authentic Integration of Mathematics and Technology in Inquiry-Based Sci

A type of signaling device for use with a fishing pole and line, sounds a signal whenever there is a catch on the hook, which provides a pull on the fishing cord or on the fishing pole. In one embodiment a two-piece hinged frame is provided which can be forced into the ground as a standard. There is a tubular receptacle into which the fishing pole can be inserted. This receptacle is hinged to the frame and is opposed by an adjustable spring means. There is a push button mounted on the frame against which the receptacle can be pressed, against the force of the spring. This push button connects to a battery and signal means which can be a small light or horn. When the fishing pole is inserted in the socket and there is a pull on the fishing line, the receptacle will be rotated against the force of the spring and close the push button to sound the signal.
