The Ice Stopper Reservoir can be used in any above-water tip up, jig rod or hook setting system. The plastic reservoir is incredibly durable-you can stand on it and it will not break. If used correctly, it will keep your line from freezing in the water to a bone-chilling -50 degrees. The plastic reservoir holds the -50Adeg Ice Stopper Solution in place for hours of use, perfect for ice fishing on cold days and nights. You need to use the Ice Stopper Solution with this product otherwise it may not work as intended. The Ice Stopper Solution will not degrade the fishing line like other similar products. You can also use this reservoir in the summer like a slip bobber to cast your fishing line farther. Just fill it with water and cast, the reservoir will float.
