The Triton SS® Mackerel Metal Jigs are available in 4 colors and 2 sizes. These jigs will capture the attention of certain species, Mackerel in particular. Cleverly designed with two “keel-shaped” sides for a wiggling action irresistible to fish. These “heavy-weights” can reach the bottom of deep water. Add an in-line swivel and you have a most effective retriever.
