Abstract: A combination of weights for fishing while using a casting reel with a rig attached to a fishing line relies upon a first sinker lifter having a forward streamlined surface shape, an internal bore through which the fishing line can be threaded and a rear cavity and a second sinker weight having a second internal bore through which the fishing line can be threaded and can be held within the rear cavity of the sinker lifter, the sinker lifter having a specific gravity greater than, but approximately, 1.0 while the sinker weight has a specific gravity substantially greater than 1.0.

Abstract: A float, including rubber material for sensing liquid levels having a chemically resistant protective covering said float having greater resistance to attach from chemicals, such as hydrocarbons, acids, and chlorinated solvents, said float may be made to include magnets, guiding devices or sensors. Also disclosed is the method for manufacturing the float of this invention including the steps of milling acrylonitrile rubber, phenolic resin, sulfur and various additives in a Banbury mill and mixing at an elevated temperature below 250°, compression molding at up to 900 psi pressure between 250° and 350° F., cooling and filling pre made protective skin container with the mixture, closing the container and heating the sealed container to bond the mixture to the container skin.
