The frogs tongue sinker, is one unique lead fishing weight. These are designed for fishing in the surf; specifically rougher conditions. They have an aero dynamic shape, and the backside can allow them to dig in pretty well.. but rougher conditions help acheive this. The tested purpose of these fishing weights allows them to "walk" off sand bars, and to move a little on current. If you prefer to sink them in deeper, you can attempt to put some tension on your line and burrow them into the sand.
Ocean-Angler is one of the VERY FEW companies to carry and supply frogs tongue fishing weight sinkers. We currently carry in 8oz, 10oz, and 12oz sizes.
