This is the vane that has dropped more jaws, hung more trophies, convinced more skeptics, and provided more big silly grins than all the "Knock-Off", "Wanna-Be", "Copy-Cat" vanes combined! This is the vane that, hands down, out-performed them all! The Blazer® Vane, with its unique design, begins steering and correcting immediately - making believers out of bow hunters and target shooters alike all over the world. 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. We recommend fletching the Blazer® vanes helically for perfect results. Blazer® vanes are designed to be used with both fixed and mechanical broadheads, yet also outperform with field points for target shooting. Bohning® has optimized the steerage capabilities and overall performance with tighter tolerances, making the Blazer® the lightest, high performance broadhead vane ever produced. *Blazer ® Vanes are 1.987" long, with a profile height of .568" and weigh just 6 grains!
