looks pretty good, but not sure... watching the video ya need arrow speed and drag... without owning a "velocitip" drag is calculated for vanes vrs feathers only... but 3 inch blazer vanes with straight fletch drag is a lot less then 4 inch vanes with 3 deg. helical... arrow diameter affects drag as well... we supposed to guess??
I downloaded this app after I had already sighted in my new to me Heli-M this year. I entered the required info (as close as I could) and the apps pin suggestions line up perfectly with what I had already done manually. it may not be perfect by itself, but appears it'll get ya close and help quicken the process
I have another App. 1) Grab you bow 2) Start shooting arrows 3) Begin adjusting your site 4) Shoot some more arrows 5) Make more adjustment 6) repeat 7) Hit where you want to hit
Pretty similar to a bore sighted for a gun. Gets you close then you'll just need to fine tune. Sent from my Desire HD using Tapatalk 2
