Often disregarded, always underrated, proper sinker choice can greatly increase your catch rate on virtually every species of fish. (Phil Duff Outdoors/Alamy/)
That sinker on your fishing line is much more important than you realize. The type sinker you choose, its weight, shape, and manner in which it's rigged and used can make or break a day of fishing.
In the most basic sense, a sinker is simply a chunk of metal used to take baits and lures to depths where fish are found. In most cases, weights are made of lead. But in recent years some states have made use of small lead weights unlawful because of the potential for lead poisoning in wildlife that may ingest sinkers.
Anglers must check state fishing regulations on lead weight use. Note that California, Maine, Massachusetts, New Hampshire, Vermont, and New York require lead-free weight substitutes, chiefly for small weights under one ounce, or lead weights that may be small enough to be eaten by fish or game.
Federal lands and waters also may require lead substitutes for fishing. Such alternative lead weights (made of steel, tin, tungsten, and alloys) are more expensive than lead. But they've come down in price in recent years and are not cost-prohibitive. They manufactured by many companies, including Eagle Claw and sold by large retailers such as Cabela's and Bass Pro Shops.
While lead weight substitutes such as spark plugs, lug nuts, and pieces of bricks have been used successfully to take baits deep to fish, there's no question that sinkers designed specifically for situational angling are best for that purpose. For practical fishing purposes, treat all lead and non-lead sinkers the same, since physical shape, design, and weight of a sinker are the key issues in their proper use.
