The Frog Tongue Sinker is molded in a unique shape that provides several benefits for surf anglers. Frog Tongue Sinkers are highly aerodynamic which helps them cast great distances, while their flattened profile creates a stable base for them to lay on their side while on the bottom and resist being taken by the current. The notched shape near the line tie helps the sinker work its way into the sand with the undertow, creating a secure hold.
