An integral molded metal sinker has a streamlined body with a pair of wings and a keel fin projecting therefrom. The body has a bulbous, semi-spherical front end which tapers back smoothly to a relatively small rear end. A wire is embedded in the body and extends from the rear end to the front end thereof. Swivels are connected to opposite ends of the wire for attaching the sinker to a fishing line and to a leader. The rear swivel is near the central axis of the body, but the front swivel is substantially above the central axis of the body, thereby placing the center of gravity of the body substantially below the front swivel and tending to prevent rotation of the body. The leading edge portions of the wings are angled downwardly with respect to the rear portions to make the sinker tend to dive when it is drawn through the water. The downturned wing portions are substantially rectangular in shape to maximize their area for a given wing span and width.
An integrally molded trolling sinker comprising a streamlined body with two wings and at least one fin projecting from the body, means connected to the front of the body for attachment to a fishing line, means connected to the rear of the body for attachment to a fishing leader, said body having a bulbous semi-spherical front end which tapers down to a relatively small rear end, said wings being disposed rearwardly from the bulbous front end of the body so that said bulbous front end disposes a substantial part of the weight of the sinker forwardly of the wings, the front portion of said wings being larger in area than the rear portions thereof and angled downwardly with respect to the rear portion thereof to cause the sinker to tend to dive when it is drawn through the water, the rear portion of said wings tapering rearwardly from the front portions and being disposed between the top and bottom of the body.
