The Mustad Duo Lock snap is a fine presentation swivel with no compromise on strength. Using small lures or crankbaits, a heavy snap will alter the balance and action of the lure, not the Duo Snap. The wide round bend also provides a larger hanging area, which will allow the bait to swing more freely for a natural presentation. When choosing a snap always go small. Pick a snap, which will match the breaking strength of your line. When tying your fishing line to the snap eye make sure to center the knot, as this will ensure the best presentation.
