Reduces line twist when casting large, wind resistant flies

Adding a swivel between the tapered section of your leader and the tippet allows the tippet and fly to spin without twisting the rest of your system, resulting in smooth, tangle-free casting all day long.

Swivels are also useful in long indicator leaders used in stillwater. By adding a swivel, the angler can add weight and also create a “stopper” for a dropper leg and fly to rest on after a fish has taken the fly.
