Saltwater fishing tackle ranges from tiny shad jigs to giant shark hooks. Whether you're  saltwater flats fishing with light tackle or  deep-sea fishing using heavy tackle, many of the same saltwater fishing techniques apply. There may be a dozen ways to catch the same species, and many techniques will work for more than one type of fish. Knowing how to use your tackle is as important as knowing where to find fish and how to lure and catch them.
