I just bought a Hindsight II last Saturday. Put it on last night and was fussin' around trying to get it sighted in. Almost had it and made some minor adjustment, then spent the next half hour crawling around in the grass trying to locate my arrow! I love the way it makes you use correct form and it definetly helps my fuzzy eyes. If someone could tell me an easy way to adjust them, I'd be a happy camper!
