Overview
An 8 pack of 1/8 ounce tungsten sinkers from Reaction, finished in a green pumpkin color and sold specifically as fishing weights rather than as a decorative accessory.
Tungsten is denser than lead, so a tungsten sinker of the same weight runs smaller and transmits more feel through the line, which matters for anglers fishing soft plastics who want to sense bottom contact. Green pumpkin is a common natural color choice meant to blend with typical bass water rather than stand out.
- 8 pack of sinkers
- 1/8 ounce each
- Tungsten construction
- Green pumpkin color
Who it's for
Bass anglers using soft plastic rigs who want a compact, dense sinker that telegraphs bottom feel, and who want a natural green pumpkin color to match their setup.
Strengths and trade-offs
Drawn from this product's published specifications.
- Tungsten density gives a compact size for the weight
- 8 pack covers multiple rigs before restocking
- Green pumpkin color blends with typical bass water
- Only offered at 1/8 ounce in this listing
- Tungsten sinkers typically cost more than lead equivalents
Performance notes
Tungsten's density lets a 1/8 ounce weight sit smaller than the equivalent in lead, which keeps it more compact on the line and transmits bottom contact more directly through the rod.
