field. You can press START to use this value. You can manually enter a value by pressing DOWN or UP. NOTE: The DOF is used only for calculating the Coriolis effect. If you are shooting at a target less than 1,000 yards away, this input field is optional. Elevation: The vertical portion of the aiming solution, displayed in milliradians (mil) or minute of angle (MOA). RNG: The distance to the target, displayed in yards or meters. Input field. W 1/2: The wind speed 1, wind speed 2, and wind direction. For example, if the wind direction (DIR) is 9:00, the wind is blowing left to right as viewed by the shooter. Input field. NOTE: The wind speed 2 field is optional. Using both wind speed 1 and wind speed 2 is not an effective way to account for different wind speeds at different distances between you and the target. Using these fields is a way to bracket (isolate) the wind values and calculate minimum and maximum windage values for the solution. 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). Additional Output Fields Aero. Jump. Effect: The amount of the elevation solution attributed to aerodynamic jump. Aerodynamic jump is the vertical deflection of the bullet due to a crosswind. Aerodynamic jump is calculated based on the wind speed 1 value. If there is no crosswind component or wind value, this value is zero. Bullet Drop: The total drop the bullet experiences along its flight path, displayed in inches. Cos. Incl. Ang.: The cosine of the inclination angle to the target. H. Cor. Effect: The horizontal Coriolis effect. The horizontal Coriolis effect is the amount of the 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 extended range. Lead: The horizontal correction needed to hit a target moving left or right at a given speed. TIP: When you enter the speed of your target, the device factors the necessary windage required into the total windage value. Max. Ord.: The maximum ordinance. 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. Remaining Energy: The remaining energy of the bullet at target impact, displayed in foot-pounds of force (ft. lbf) or joules (J). Spin Drift: The amount of the windage solution attributed to the 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. Time of Flight: The time of flight, which indicates the time required for a bullet to reach its target at a given range. V. Cor. Effect: The vertical Coriolis effect. The vertical Coriolis effect is the amount of the 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 extended range. Velocity: The estimated velocity of the bullet when it impacts the target. Velocity Mach: The estimated velocity of the bullet when it impacts the target, displayed as a factor of mach speed. Environment Fields Amb/Stn Pressure: The ambient (station) pressure. Ambient pressure is not adjusted to represent sea level (barometric) pressure. Ambient pressure is required for the ballistics shooting solution. Input field. TIP: You can manually enter this value, or you can select the Use Current Pressure option to use the pressure value from the internal sensor in the device. Humidity: The percentage of moisture in the air. Input field. Latitude: The horizontal location on the Earth's surface. Negative values are below the equator. Positive values are above the equator. This value is used to calculate the vertical and horizontal Coriolis drift. Input field. TIP: You can select the Use Current Position option to use the GPS coordinates from your device. NOTE: The Latitude is used only for calculating the Coriolis effect. If you are shooting at a target less than 1,000 yards away, this input field is optional. Temperature: The temperature at your current location. Input field. TIP: You can manually enter the temperature reading from a connected tempe sensor or other temperature source. This field does not automatically update when connected to a tempe sensor. Wind Direction: The direction from which the wind is coming. For example, a 9:00 wind blows from your left to your right. Input field. Wind Speed 1: The wind speed used in the shooting solution. Input field. Wind Speed 2: An optional, additional wind speed used in the shooting solution. Input field. TIP: You can use two wind speeds to calculate a windage solution that contains a high and low value. Applied Ballistics® 31
