Bushnell Fusion 1600 ARC 12x50 Owner's Manual - Page 17

If in BOW mode, the line of sight distance will display in the primary numeric display and the inclination and horizontal distance will display in the secondary numeric displays. Bushnell determined through extensive testing and interviews with high-profile bow hunting experts that multiple bow ballistic groups were not necessary. Bow-hunters want to know true horizontal distance because that is how they practice shooting, and once they confidently know that, they can make any necessary adjustments. Giving the bow-hunter anything else other than horizontal distance creates additional confusion and uncertainty. Many people mistakenly believe that uphill shots perform differently from downhill shots because of gravity. However, it is not due to gravity, but more of an aberration of the sighting system used on bows. The sighting pin on a bow resides several inches above the mechanical axis of the arrow. For example, when one is aiming 23 degrees up an incline, the arrow is at a different angle. RIFLE MODE EXAMPLE Line of sight is 376 yards, angle is -33 degrees, and the bullet-drop/holdover is 28 inches. ARC not only takes into account ballistic data based off your caliber and load from distances of 100-800 yards, but also compensates for any uphill and downhill angles which also affect bullet-drop. Line of Sight = 376 Yards Degree of Angle = -33° Line of Sight = 376 Yards Holdover/Bulletdrop = 28 Inches 17
