Contact Arrow Calculator
Questions about arrow speed, FOC, weight, spine, IBO formulas, or bow tuning? Spotted a calculation that doesn't match your chronograph? We help bowhunters, target archers, tuners, and instructors get the numbers right before they head to the range.
How do I get a faster reply?
Paste the exact inputs from the calculator (IBO rating, draw length, draw weight, arrow components, string weight) and tell us which tool — Speed, FOC, Weight, or Spine — plus the output you expected. A screenshot or the page URL helps even more.
Do you offer live chat or phone?
Not yet — email lets us verify every calculation against the actual formulas before we reply. We read every message and answer most within two business days.
Can you verify my setup for hunting?
For planning questions, yes — we can help cross-check speed, KE, FOC, and spine numbers. For legal compliance, always verify your state's hunting regulations and consult local wildlife officials.
