The Air Vane is designed for small diameter arrows shot at long distances and it has quickly become Bohning's #1 selling vane for Fita and Field Archery. We also recommend it for 3D when shooting with small diameter arrows. It's a great choice for compound and recurve shooters alike as its low profile minimizes contact with the arrow rest, and its small surface area reduces the effects of crosswind drift. The Air Vane measures 2 (50.8mm) in length, 0.3 (7.6mm) in height and weighs 4.5 grains. Like all Bohning vanes, the base of the Air Vane is pre-primed for optimal adhesion. A little history of the development of the Air Vane: In 2015 Bohning teamed up with world-class archers Pierre-Julien Deloche and Dominique Genet in the development of a new outdoor vane for longer distances and volatile weather conditions. Genet specifically wanted the same low-profile as the Ice Vane but with an X-Vane inspired tail as those are the two vanes he had obtained the best results with.
