The Impulse® Vane is recommended for recurve shooters and is the result of over two years of research in aerodynamics and materials engineering. The material is impregnated with microscopic glass beads, rendering it lightweight and flexible but still durable. The ultra-low profile is ideal for minimizing the effects of crosswinds and wind gusts. The 4" (101.6mm) Impulse Vane measures 0.3" (7.6mm) in height and weighs an average of 5.0 grains (324 mg). Like all Bohning vanes, the base of the Impulse Vane is pre-primed for optimal adhesion.
Proudly manufactured at the Bohning Factory in Lake City, Michigan, United States.
