Upon returning to the normal operating menu, the current compensation mode and unit of measure will be identified in the LCD as indicated below. SETUP menu Normal Operating Menu When the unit automatically powers down, operation will always return to the normal operation (i.e. away from SETUP) with the last used ARC mode active (i.e. BOW, RIFLE, or REGULAR) along with the last used TARGETING modes active (Standard SCAN, BULLSEYE, or BRUSH). If the unit turns off while in the SETUP menu, the unit will always return to the last mode(s) still active. Once the range is displayed, continue to hold the POWER button down for approximately 2 seconds while holding the aiming circle on the object and keeping the unit as steady as possible so as to allow the inclinometer enough time to measure angle. Then release the POWER button. Once you have released the power button, a degree of angle and compensated range will be displayed beneath the line of sight distance as seen in the images below. BOW MODE EXAMPLE Line of sight is 32 yards, angle is -44 degrees, and the Angle Range Compensated distance is 23 yards. The “ ” means “play” or “shoot as,” so instead of shooting as 32 yards, shoot as 23 yards. If you were to shoot as if 32 yards, you would shoot over the top of the deer because of the severe angle. 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. If in RIFLE mode, the ballistic group will be displayed in the bullet drop numeric field anytime that the primary numeric display is showing dashes (i.e. no target acquired). When a target is acquired in RIFLE mode, the line of sight distance will display in the secondary numeric displays. The “IN” icon (i.e. inches) will light next to the bullet drop numeric display, if the unit of measure is set to Yards (Y). If the unit of measure is set to Meters (M), the bullet drop will be calculated and displayed in centimeters and the “IN” icon will be turned off. If the bullet drop / hold over number is blinking, this means the user should add 100 to the number blinking. REGULAR MODE This mode does not provide any degree of elevation or compensated distance, but instead, line of sight distance only. The will still appear below the line of sight numeric display, but there will not be any information displayed in this secondary numeric display. Regular Mode KNOWING WHICH BALLISTIC GROUP TO SELECT Bushnell engineers have worked with Sierra® Bullets’ ballistic programs and grouped many of the most popular calibers and loads into eight ballistic groups (A,B,C,D,E,F,G,H). Once you know what caliber and load you are shooting simply look through the chart to determine which one of the eight ballistic groups match with your particular load and caliber. For Muzzleloaders, we have worked with PowerBelt Bullets to incorporate ballistic data into two ballistic groups (I and J).
