Guide Review - Invisible Fluorocarbon Swivels from Aquateko
Since the invisible fluorocarbon swivel is neutral buoyancy, it will not pull your line down. This can be a benefit if you are fishing a soft jerk bait and don't want it to sink fast. The neutral buoyancy means it won't pull the nose of the bait down, but will let is sink in a natural manner.
One claim made by some is this neutral buoyancy helps when fishing a Carolina Rig, but, since the swivel butts up against the sinker on a Carolina Rig, I do not see the benefit, unless you let the fish "run" with the bait and pull the line through the sinker. I think that is a good way to miss strikes that you would hook if you set the hook as soon as the fish takes the bait.
The swivels come in different pound-test strengths. I tied a 12 pound swivel to 12 pound PLine Fluorocarbon and the line broke before the swivel. With the clear line and swivel, I had a hard time keeping up with the test equipment, it kept disappearing on my desk!
The swivels are expensive, at about a dollar each, so I would not use them unless they were helping in the way I was fishing. That is not more expensive than a good ball bearing steel swivel, so if you use them your cost would not go up to switch and these swivels do not corrode!
The line tie on each end of the swivel is designed so the line will not slip around the tie, and keeps it straight.
