Ringer Swivels are a great invention that makes rigging baits so much easier. The key is  the rubber o-ring connected to one end of the swivel. If you're fishing in an offshore tournament that requires a circle hook, using a Ringer Swivel is the easiest and most efficient way to connect your hook to your bait. It will lead to more hookups. If you go offshore and fish ballyhoo, bring a few packs of Ringer Swivels. Use them when targeting all different kinds of marlin. 

Ringer Models are available in four sizes.

Models: Size 1, Size 2, Size 3, Size 4
