The Junk Proof Hook in Ultima Online is a special item that can be attached to a fishing pole to prevent the catching of unwanted items, specifically footwear. This hook is one of the rewards from the Professional Fisher Quests and requires the High Seas booster pack to use. When applied, it ensures that all catches are meaningful, improving the efficiency of your fishing endeavors. The hook has a finite number of uses, typically 50, and will disappear once exhausted, reverting the fishing pole to its original state
