Angles Screen


Target Angle: This is used for a moving target. The angle is the direction the target is moving relative to your line of sight. 0 degrees for a target moving towards you, 90 degrees for a target moving perpendicular to the line of sight, and 180 degrees for a target moving away from you.
Target Speed: This is used for a moving target. Enter the speed of the target, relative to you. If moving to your right, the value is positive. If moving to your left, the value is negative. This measurement is in feet per second.
Minimum Range: The shortest distance you want to see listed in the drop table. This measurement is in yards.
Range Increment: The interval between listings in the drop table. This measurement is in yards.
Maximum Range: The maximum range you want to see listed in the drop table. This measurement is in yards.
Cant Angle: The angle the rifle or pistol is tilted. Positive values for a tilt to the right and a negative value for a tilt to the left. This measurement is in degrees.
LOS-Angle: The angle between your line of sight and the ground. Positive values are for shooting uphill and negative values are for shooting downhill.
Clicks per MOA: The drop table will display the number of "clicks" you need to adjust your scope for a particular distance. You will need to enter the number of "clicks" your scope requires to move 1 MOA (Minute of Angle). A lot of scopes are set to move 1/4 MOA per "click". This would correspond to the value of 4 for the entry box.
Ele Corr for Zero: This checkbox causes the elevation to be raised so the projectile's path will cross the line of sight at the zeroed range. If the box is unchecked, you will see the projectile's path as it falls from the muzzle to the ground.
Az Corr for Zero: This checkbox causes the azimuth of the barrel to be corrected for wind so the projectile will cross the line of sight at the zeroed range. This box will usually be unchecked.
