This device modifies the vane shape as a propeller, allowing an increase in arrow revolution for more stability and accuracy. The process is simple, take your existing arrow shaft with the vane already attached, warm it with a heat gun for a few seconds in order to allow the vane to soften. Then, place the Twister Vane from the nock end of the arrow and gently rotate the Twister Vane in the same direction of the helical angle. Next, allow at least 30 seconds for cooling time so the vane may retain the shape of the Twister Vane. Lastly, remove the Twister Vane.
Includes: 1 Twister Vane LARGE
