The product of significant research and testing, the Elite Tungsten Flipping Weights feature a 97% tungsten and 3% nickel composition. Significantly harder and more compact than lead, they slip through small holes in cover more easily and help you feel everything your bait bumps into - for better bite detection. The line holes are also diamond bored for extreme smoothness so they won't fray your line, and durable, sealed paint finishes in a variety of colors help you better match the weights with your baits. Rest assured, the Elite Series Flipping Weights will give you the edge you need to boat more bass and cash more checks.
