Storm sinkers also known as Hatteras sinkers are a modified version of pyramid sinkers. The shape is still a pyramid at the top but with a longer rounded point, some have a ball on the end instead of the point. Storm sinkers will dig into the sand more and are easier to retrieve than the larger sinkers that hold bottom for rough conditions such as a frog’s tongue. Breaking waves create a sort of quick sand that will engulf your sinkers and make it difficult to retrieve. The storm sinkers pull out of that quick sand much easier.
Storm sinkers come in three and four sided versions.
Once it is too rough for storm sinkers you need to move up to a surf claw or Sputnik sinker.
Storm sinkers and others shaped like them can impale fish when they land in a school. Bunker Impale of The Year.
