A light sliding sinker for finesse inshore live bait work.
The sliding design is the whole point. Line runs free through the sinker, so a snook or a red picking up the bait feels nothing and does not drop it before you come tight.
Three-eighths is light enough to keep a shrimp or a small baitfish swimming naturally while still getting it below the surface layer.
The egg shape rolls over shell and rock instead of wedging.
