The Magna EWG Joint is used with artificial lures when the rig needs to navigate through obstacles while remaining effective on the bottom. The IRON-JOINT head provides a useful articulation for scraping, lifting, and then re-establishing contact with the substrate without completely locking the lure in place. Its clip holds the hook in place and maintains a consistent rig during vigorous retrieves. Size 5/0 is suitable for more compact lures, while sizes 6/0 and 7/0 are designed for larger lures or heavier weights. The weight should be chosen based on depth, current, and the desired speed of contact with the bottom.
