Customized shape tungsten alloy fishing weights
we all know, Density is desirable as weights must be as small as possible, in order to minimize visual cues which could drive fish away from a fishing operation. tungsten tungalloy has a density of 14.5-19g/cm3. while the lead is only 11.3g/cm3.
that says, in the same size, the tungalloy or tungsten sinker is much heavier than the lead sinker. Actually feel what you have been missing! Smaller, dense tungsten is super sensitive, allowing you to detect more strikes and catch more fish while greatly reducing hang-ups! Special "seal coat" painting resists chips and scratches.
largemouth bass fisherman, tungsten sinker!
