Barrel swivels provide a number of benefits and are primarily used when using strike indicator systems. They help:
- Reduce leader tangles
- Add inline weight that won't fly off like split shot
- Help prevent Quick Release Indicator and peg loss in the event of a break-off
- Help identity proper fly depth, as fish will take a swivel
- Reduce leader twist when using water boatmen and backswimmer patterns with extended legs
- Provide an element of attraction due to the flash they give off in the water
