The rubber grommet on the top of the Surface Bomb allows you to add water, whilst also providing a highly visual sight bob when fishing. This versatile controller float is aerodynamic thanks to the weight-forward pear drop design, which also provides a bolt effect, due to the resistance on taking fish at the front of the float. Comes complete with our specially designed quickchange stem, which can be used a multitude of beads and swivels to provide a safe, semi-fixed setup. Available in two sizes.
