A slip sinker includes an elongated inner tubular weighted mass having a conical end for ease of threading a fishing line. Annularly disposed about the elongated inner tubular weighted mass is a casing shell that provides a level of buoyancy and which has a generally bulged, symmetrical, and cylindrical or oblong shape. The casing shell is a durable, buoyant, low-density element. The slip sinker has a shape and density which causes the sinker to be slow to sink, to land softly, to make less noise, and to avoid digging into bottom substrates. The disclosed slip sinker: does not easily tangle in weeds or other bottom substrates; starts to ascend immediately upon the line being tugged or reeled, such as to avoid dragging across the bottom of the body of water and/or catching on obstacles; and improves ease of casting, such as by allowing for improved control and farther casts.
