"Shooting two different set ups and arrow configs, makes it easy to dial the bitz back in for the opposite arrow."
"Quick and simple check to keep things consistent"
"The DCA vane tool is nice to see how steep of angle you want to flectch your vanes."
"Easy to use and helps ensure I’m getting the exact degree I’m after."
"Works great with a Bitzenburger jig, easy to set up and adjust for precise vane angles. Once you find your preferred settings, write them down, and you can quickly reset your jig for consistent, repeatable arrow builds every time."
"I probably should have looked into this more. I think it is what it said it was but I think the indications on my OMP Fletching Jig are probably sufficient for what I needed."
"Works great makes it super easy to see the angle your applying your vanes at. No more guessing."
"This is exactly what I needed to get that 2. 5 degree helical that DCA recommends for their vanes."
"This is a simple and genius tool for those who love to fletch their own arrows. Works great, is reasonably priced, and is easy to store with the jig and related tools."
"Perfect for finding offsets."
