The Heat Vane is designed for bows that require a lower profile vane. It has the same surface area as our Blazer vane but is only 0.44" (11.3mm) high. This allows you to shoot this vane out of bows or rests that have lower clearance levels. This vane is perfect, 3-fletched, to steer a mechanical broadhead or 4-fletched with a fixed-blade broadhead. Bohning's AR1250 Material is a stiffer material that allows for fast, ultra-quiet flight over longer distances. Our stiffer material also provides maximum speeds when fletched at a 1 degree offset, while staying silent. Bohning AR1250 is also our lightest material. All Bohning vanes are pre-primed and do not require vane cleaning or pen primers. We recommend BlazerBond® or Fletch Fuse® adhesives for best adhesion.
