Abstract
Abstract An improved fishing sinker having an elongated cylindricalshaped body of hollow construction is closed-off at its ends to define an air space therein, and carries weight or ballast means at its lower end. A ringlike connector is mounted on the body for up and down movement therealong, and latching finger means is provided for retaining the ring in one of a selected group of positions to provide different points of connection of a fishing line thereto. Ballast means of different characteristics or weight may be used interchangeably with the body.
