start off about 5 to ten yards and see where the arrows hittin...then move the sight pin to where the arrow hits dead center....step back to 10-15 yards this is where you should sight ur first pin in ...shoot it a few times and adjust the sights till its accurate ...step back the distance you want ur next pin...( mines 25 yrds)....then the last pin...( mines at 30-35) thats how i tune mine up and check all the ranges once more with ur sighted pins to make sure they're accurate....
