Spare spool for the PENN® Tidal XT, available in size 8000 and 7000. A spare spool allows for extra flexibility when the situation changes on the bank or when you want to change tactics, it is not always practical to take several rods and reels with you. Being able to quickly change setup by means of a new spare spool with a different type of line is an economical and quick alternative to a completely new rod with reel.
