The Turbo Launcher eliminates untangling lines and saves time by only walking the length of your lines one time! It also allows you to let out your lines with the kite attached so that you can launch in areas where you can't lay out the entire length of your lines. It is designed specifically for launching in the water where there isn't a large beach or from a boat. Or you could just use it to get out on the water quickly, without having to worry about untangling your lines.
