Freshwater Raft Fishing Sinker Principles
- Sinker sizes (e.g., #1.0) indicate buoyancy level, not weight in grams.
- Thread two matching rubber sleeves onto the main line and insert both ends of the copper sinker.
- Smaller sinkers and thinner rod tips yield clearer bite signals. Choose lighter sinkers for softer rod tips.
- Use heavier sinkers in fast current or strong wind for stability, or when small fish interfere at shallow depths to sink bait quickly to the bottom.
