This clever sinker design offers anglers an aerodynamic shape that is excellent for maximising casting distance while also providing good bottom grip with four wire prongs. These prongs can then free the weight from its holding position as the wires "break away", folding back, when a fish strikes or the angler winds in. Breakaway sinkers are popular with beach and rock anglers fishing areas with high water movement and/or areas with seafloors that can cause other sinker shapes to snag on obstructions.
