ABSTRACT:
This invention relates to an ice fishing tip-up and more particularly to a means for activating an audible or visual indicator to alert a fisherman when a fish has engaged a hook of the ice fishing tip-up. The device is comprised of a switch which interconnects the audible or visual indicator to a power source. The switch has terminals normally biased toward a closed position whereby a first terminal is in contact with a second terminal. An insulator is placed between the terminals of the switch such that the terminals are not in contact. The insulator is then removed from between the terminals in response to an increase in tension in the fishing line when a fish strikes the hook. The removal of the insulator from between terminals causes the switch to close, thereby activating the audible or visual signal to alert the fisherman.
