COG is a special tool for finding the optimal balance of the dart.
Thanks to accurate information about the center of gravity of your darts, you can make informed decisions about changing shafts, flights and tips, according to the way you shoot.
To find the center of gravity of the dart, place the COG tool on a flat surface, place the dart in the tool and move it so that the spirit level bubble is centered. The center of gravity of your dart is then at the point of the arrow "0".
