Sinkers are small weights used in fishing to help cast bait deeper into the water. They are typically made of materials like lead or tungsten and come in various shapes and sizes. By adding a sinker to the fishing line, anglers can ensure that their bait reaches the desired depth where fish, such as bass or trout, are more likely to be found. When using sinkers, it's important to choose the right weight for the type of fishing being done. Heavier sinkers are useful in fast-moving water, while lighter ones work well in calm conditions. Properly using sinkers can significantly improve the chances of a successful catch.
