The Mustad High-Speed Multi Link Swivel range is designed for trolling, especially high-speed trolling, to eliminate line twist and make a dependable and strong link between the main line and a leader. The special design will also send bubbles over the trailing lure to make it look like the lure has come alive. You can also use it when fishing with bombarda floats to prevent line twist. When choosing a swivel always go small. Pick a swivel, which will match the breaking strength of your line. This will give the best performance and presentation. When tying your fishing line to the swivel eye make sure to center the knot, as this will ensure the best rotation. Made from brass, for either saltwater or freshwater use. Comes in 11 different sizes and breaking strengths. Black nickel finish.
