The Angle Cosine Indicator(ACI) takes the confusion out of determining shot angle. No need for angle and cosine charts, one simple calculation is all you need. After determining the range to your target, multiply that distance by the cosine value, which is marked on the ACI with a single red hash mark. This calculated value will be your corrected distance for angle.
