The Water Gremlin Round Split Shots are very useful for adding weight to your line in small increments, while avoiding any potentially line-weakening knots. Current, depth, and wind are all factors that will change the weight you need to keep your lure on the bottom, and the Water Gremlin Round Split Shots are perfect for the task. Round split shots also get through the rocks and other underwater obstructions more easily than the removable types. The lower the number, the larger the shot, and the number two's weigh about 3/16 ounce. The Water Gremlin Round Split Shots are perfect for finesse presentations.
