If you happen to switch fishing lures more often than not, using a snap swivel really helps. Using a snap swivel when trolling minimizes line twist and proves to be very beneficial when the fishing lure becomes tangled after you miss a strike. A swivel comprises two metal eyelets that are independent of each other and round in shape. The two are connected with the help of two separate round metal eyelets. These eyelets are connected to one another with the help of a barrel fitting. The eyelets are in no way dependent on each other and turn without any hindrance in the fitting.
A swivel with snaps looks like a safety pin. To attach all you have to do is open the snap. This permits weights, leaders and other tackle to be attached to the swivel. The costlier swivels come with ball bearings in the barrel connector. This makes sure rotation is more consistent and seamless.
