Salamander Sinkers is outstanding for casting and trolling. Each sinker has a recess on the front that allows water to enter and leave under force in 360 degrees. This force causes the sinker to track in a straight line without wobbling or tumbling regardless of retrieval speed. The recess front is also used to serve as part of the snag resistant feature of the sinker. It acts like a bumper when it hits a rock or obstruction and bounces off.
