The Blazer® Vane is designed for steering fixed-blade broadheads and has been the #1 hunting vane for over 10 years! It measures 1.5" (38.1mm) in length, 0.49" (10.16mm) in height, and weighs an average of 4.5 grains. Like all Bohning vanes, the base of the Blazer Vane is pre-primed for optimal adhesion. The Blazer® Vane 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-performs them all! It's designed for fixed-blade broadheads but is also perfect for crossbows and 3D archery. The Blazer® Vane, with its unique design, begins steering and correcting immediately - making believers out of bow hunters and target shooters alike! The combination of the steep leading edge angle and its material properties enables 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 also makes 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 Blazer® vanes with a helical for perfect results. What's in your quiver? If it doesn't say Blazer® and carry the Bohning® logo, it's not a REAL BLAZER. Only Bohning makes the Blazer Vane, and we proudly print our name on each one. It's not just the profile that sets us apart from look-a-likes, our proprietary material has been tested in extreme conditions to make sure it doesn't fail you when it really counts. Don't be fooled by copycats. If it doesn't say Bohning, it's not a Blazer and it won't perform like one. Proudly manufactured at the Bohning Factory in Lake City, Michigan, United States.
