Extreme up- and downhill angles alter true shooting distances and point of impact. Bushnell ARC accounts for the terrain angle when calculating distance, so you know precisely where to aim, with your bow or rifle.
In Bow Mode, Bushnell ARC provides true horizonal or "shoots-like" distances from 5-99 yards, so you always know what pin to use, no matter the angle.
With a one-time calibration that takes seconds, Bushnell ARC provides bullet-drop/holdover data for your specific caliber and load. (Over 2,000 caliber/load combinations, plus muzzleloaders).
