I am a mechanical engineer with 20+ years in R&D / product development with approximately 30 patents to my name. Including a patent for the Sabre Series of vane and the Vane Angle Tool. I took a deep dive into tuning arrows using my own calculations and spreadsheets along with existing software. Then further refined these calculations with years of testing. I started this company because I hated to see people walk into an archery shop and the guy behind the counter grabs a hand full of shafts chops them at a random length and throws some vanes on them and out the door they go. This is discouraging to the shooter because as their skills increase they will not see a change in results. On an important and possibly costly hunt, an untuned arrow could lead to a poor shot and either missing the animal or even worse not getting a clean quick kill.
