Abstract: An ice-fishing rig with a signaling device which is magnetically restrained until released by movement of the fishing reel. A pair of magnetically interactive and aligned components, secured one each to the signaling device and reel, restrain the signaling device until a fish pulls on the line and the magnetic alignment is broken, releasing the signaling device. The signaling device comprises a colored float in as transparent vertical tube which is pivotally secured to the center of crossbar member. The tube is filled with an antifreeze to permit movement of the float in cold weather. The tube is pivoted to a position essentially parallel to the crossbar members for easy storage and handling.
