Available Data Fields

• Elevation - the vertical portion of the aiming solution, displayed in milliradians (mil) or minute of angle (MOA).
• Windage 1 - the horizontal portion of the aiming solution based on the wind speed 1 and wind direction, displayed in milliradians (mil) or minute of angle (MOA).
• Windage 2 - the horizontal portion of the aiming solution based on the wind speed 2 and wind direction, displayed in milliradians (mil) or minute of angle (MOA).
• Lead - the horizontal correction needed to hit a target moving left or right at a given speed.
• Time of Flight - indicates the time required for a bullet to reach its target at a given range.
• Velocity - the estimated velocity of a bullet when it impacts the target.
• Velocity Mach - the estimated velocity of a bullet when it impacts the target displayed as a factor of Mach speed.
• Cos. Incl. Ang - the cosine of the inclination angle to the target.
• Bullet Drop - the total drop the bullet experiences along its flight path, displayed in inches.
• V. Cor. Effect - the vertical Coriolis effect, the amount of elevation solution attributed to the Coriolis effect. This is always calculated by the device, although the impact may be minimal if you are not shooting at an extended range.
• H. Cor. Effect - the horizontal Coriolis effect, the amount of windage solution attributed to the Coriolis effect. This is always calculated by the device, although the impact may be minimal if you are not shooting at an extended range.
• Aero. Jump Effect - the amount of the elevation solution attributed to aerodynamic jump. The vertical deflection of the bullet due to a crosswind. If there is no crosswind component or wind value, this value is zero.
• Spin Drift - the amount of the windage solution attributed to spin drift (gyroscopic drift). For example, in the northern hemisphere a bullet shot out of a right-hand twist barrel will always deflect slightly to the right as it travels.
• Remaining Energy - the remaining energy of a bullet at target impact, displayed in foot-pounds of force (ft. lbf) or Joules (J).
• Max. Ord - the maximum ordinance is the maximum height above the axis of the barrel that a bullet will reach along its flight path.
• Max. Ord. Range - the range at which the bullet will reach its maximum ordinance.
