Aspect Ratio (AR) is the latest dart innovation from Unicorn, which has been developed after extensive research on flight aerodynamics. The wide front profile increases stability in flight, while the narrower rear section reduces air resistance to increase speed. Unlike the standard flights, the corners of the new ARs have been deliberately designed with large, curved curves to reduce collisions and resulting rebounds. This allows a tighter throwing profile on the dartboard. Available in two cutting shapes AR1 and AR2.
