At only 2" long and 6 grains, the Blazer Vane can change the way you think about arrow guidance. The unique design helps the vane begin steering and correcting immediately. A steep leading edge angle allows air to flow over the vane and creates lift that leaves the vane inside undisturbed by air. Once in the air, the vane acts like a rudder on a ship, steering a path to success. 36 pack.
