The smoother action of ball bearing swivels allows for unobstructed line movement. As a result, they can handle tremendous amount of pressure from big fish without failing because of friction.
The snap that comes fitted to the ball bearing swivel is firm and secure attachment that won’t fail under extreme pressure or conditions. Also, with the added bonus of snap is, it becomes really easy to switch between lures or lines depending on the fish you are aiming for. Just snap the swivel to your reel and start catching plenty of fish.
