Pyramid sinkers differ from bank sinkers and cost more. Pyramid sinkers contain a brass or stainless steele eye where bank sinkers have a loop in the lead casting. Pyramid Sinkers are a practical choice when fishing water with sandy or muddy bottoms, swift currents and rough conditions. The 4-sided design of pyramid weights resists tumbling, allowing your bait rig to get in place and stay there. Pyramid Sinkers cast well, sink quickly and won't damage your line. They are the ideal choice for surf fishing.
