Product Description

Tungsten Alloy Fishing Sinkers are high-density, eco-friendly alternatives to traditional lead sinkers. With a density of up to 18.5 g/cm³, tungsten sinkers are smaller, more sensitive, and more environmentally friendly than lead weights. They sink faster, improve casting accuracy, and provide better bottom contact for enhanced fishing performance.

Ideal for bass fishing, deep-sea fishing, fly fishing, and saltwater fishing, these precision-engineered sinkers come in a variety of shapes & sizes to meet different fishing techniques.
