InvisaSwivel is a clear fishing swivel that was developed for the avid fisherman who wants to catch more fish. This stealth design is invisible in water. Fish cannot see the swivel like conventional metal swivels that are heavy and corrode which affects their ability to properly remove line twist. Another great feature of the InvisaSwivel is its ability to self lubricat. These swivels will protect your guides from nicks by gliding softly through causing no damage unlike a metal swivel. A conventional swivel can only be bent 3-4 times before they break. InvisaSwivels can be bent hundreds of times and show no signs of fatigue, continue to swivel and bend right back. Corrosion plays a huge part in metal swivel failure. Water and humidity eat away the metal the minute the package is opened. InvisaSwivels are not affected by salt or fresh water so corrosion is never an issue.
