The use of a swivel prevents the line from twisting, provides free rotation without much effort, increases reliability when fishing with strong currents and helps to quickly change equipment elements.

The swivel with a snap hook allows you to quickly change the bait or leash. For the same purpose, use a swivel with a fastener. Triple swivels are most commonly used for feeder rigs.

A carabiner with a fastener is extremely convenient for changing lures, and in a spinning lure it is a very important advantage, because in case of an unsuccessful bite, you need to try a large number of different lures.
