The Rocket Bobber from Bill Lewis Outdoors uses an aerodynamic design that allows you to get your bait out where the fish are and flies tip first through the air for better accuracy. Ultrasensitive design lies flat on the water so the lightest nibble makes the tip move up so you can quickly and easily detect bites. Can be fished vertically by adding weight to your rig. Two halves are sonic-welded for maximum strength. Built-in hook remover. Per 2. Sizes: Ultralight (3.75), Medium Jr. (4.75), Large (6.25). Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Floats.
