The Bohning Archery Blazer 2 inch Broadhead Vane is the one that has hung more trophies dropped more jaws and convinced more skeptics than all the Wanna Be vanes combined! This is the vane that, hands down, out-performed them all! The Bohning Archery Blazer 2 inch Broadhead Vane, with its unique design, begins steering and correcting immediately. The combination of the steep leading edge angle and material stiffness enables the air to flow over the vane in a manner that actually creates lift. This leaves the tip of each vane inside undisturbed air, similar to the drafting principle used in auto racing. This airflow created by the precise leading edge angle allows the tip of each vane to act like a rudder, which is noticeable at longer distances with the flatter trajectory Blazer Vanes provide. Bohning Archery Blazer 2 inch Broadhead Vanes are 1.987 inches long, with a profile height of .568 inches and weigh just 6 grains. And they work great for cross bow bolts too.
