Sea Striker surf sinkers prevent your weight from moving in the surf. The stainless steel arms lock in place and anchor in the sand. When you are ready to retrieve, pull on the line and the arms snap open to allow for easy retrieval. The sinker on the left shows the set position, while the sinker on the right shows the tripped (retrieval) position. Surf Sinker - 3.5 oz SS100G$3.49 Surf Sinker - 5.3 oz.
