I hear so much on here and other site's about people testing with a chrony. Usually, my first question is, "Why?" I mean, my 45 lb. bow, shoot's an arrow at what I would assume is a slow speed. I can watch the ark from 30 yards, and it just isn't as fast as I've seen other bows shoot. But I'm not about to go lay down the dough on a chrony just so I have the "closure" of knowing what the EXACT speed is. I'm just trying to get it. If my bow can shoot an arrow through a bale of hay, isn't that fast enough?
