This handy tool utilises the entire Evolusion Arrows product range plus recommended arrow vanes to calculate total arrow weight, total GPI (grains per inch) and GPP (grains per pound).
Check your nocks regularly! If they show signs of damage, cracking or are a loose fit, replace them immediately. Choose the right arrow spine for your bow setup. Read our Spine Charts here. Use our Arrow Weight Calculator here. Find our Stay Arrow Safe Guide here.
