Quick Edit Fields

DIR

The direction from which the wind is coming. For example, a 9:00 wind blows from your left to your right. Input field.

DOF

The direction of fire, with north at 0 degrees and east at 90 degrees. Input field.

Elevation

The vertical portion of the aiming solution, displayed in inches, milliradians (mrad/mil), or minute of angle (MOA).

RNG

The distance to the target, displayed in yards or meters. Input field.

W 1

The wind speed used in the shooting solution, displayed in miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s). Input field.

W 2

An optional, additional wind speed used in the shooting solution, displayed in miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s). Input field.

TIP: You can use two wind speeds to calculate a windage solution that contains a high and low value. The actual windage to apply for the shot should fall in this range. 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.

Range Card Fields

Bullet Drop

The total drop the bullet experiences along its flight path, displayed in inches, centimeters, or millimeters.

Elevation

The vertical portion of the aiming solution, displayed in inches, milliradians (mrad/mil), or minute of angle (MOA).

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

TIP: When you enter the speed of your target, the device factors the necessary windage required into the total windage value.

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 Mach

The estimated velocity of the bullet when it impacts the target, displayed as a factor of mach speed.

Windage 1

The horizontal portion of the aiming solution based on the wind speed 1 and wind direction, displayed in inches, milliradians (mrad/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 inches, milliradians (mrad/mil), or minute of angle (MOA).

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.

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.

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 Mode

Allows you to set the Direction setting relative to either your Direction of Fire (DOF) or relative to true north (True Wind Dir).

NOTE: When you are engaging multiple targets at different DOFs, the True Wind Dir option is useful because you only have to adjust your DOF, and your Direction remains the same.

Wind Speed 1

The wind speed used in the shooting solution, displayed in miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s). Input field.

Wind Speed 2

An optional, additional wind speed used in the shooting solution, displayed in miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s). Input field.

TIP: You can use two wind speeds to calculate a windage solution that contains a high and low value. The actual windage to apply for the shot should fall in this range.

Target Card Fields

Direction of Fire

The direction of fire, with north at 0 degrees and east at 90 degrees. Input field.

NOTE: The Direction of Fire 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.

Inclination

The angle of inclination of the shot. A negative value indicates a downhill shot. A positive values indicates an uphill shot. The shooting solution multiplies the vertical portion of the solution by the cosine of the inclination angle to calculate the adjusted solution for an uphill or downhill shot. Input field.

Range

The distance to the target, displayed in yards or meters. Input field.

Speed

The speed of a moving target, displayed in miles per hour (mph) or kilometers per hour (km/h). A negative value indicates a target moving left. A positive value indicates a target moving right. Input field.

Profile Fields - Bullet Data

Sight Height

The distance from the center axis of the rifle barrel to the center axis of the scope, displayed in inches or centimeters. Input field.

TIP: You can easily determine this value by measuring from the top of the bolt to the center of the windage turret, and adding half of the diameter of the bolt.

SSF Elevation

A linear multiplier that accounts for vertical scaling. Not all rifle scopes track perfectly, so the ballistics solution requires a correction to scale according to a particular rifle scope. For example, if a turret is moved 10 mil but the impact is 9 mil, the sight scale is 0.9. Input field.

SSF Windage

A linear multiplier that accounts for horizontal scaling. Not all rifle scopes track perfectly, so the ballistics solution requires a correction to scale according to a particular rifle scope. For example, if a turret is moved 10 mil but the impact is 9 mil, the sight scale is 0.9. Input field.

Twist Direction

The direction that the rifling of your barrel spirals. Most rifles have a right-handed twist. Input field.

Twist Rate

The distance it takes for the rifling of your barrel to make one full rotation. Rifle twist is often provided by the gun or barrel manufacturer. Input field.

Zero Height

An optional modification to impact elevation at zero range. This is often used when adding a suppressor or using a subsonic load. For example, if you add a suppressor and your bullet impacts the target 1 inch higher than expected, your Zero Height is 1 inch. You must set this to zero when you remove the suppressor. Input field.

Zero Offset

An optional modification to impact windage at zero range. This is often used when adding a suppressor or using a subsonic load. For example, if you add a suppressor and your bullet impacts the target 1 inch to the left of the expected impact, your Zero Offset is -1 inch. You must set this to zero when you remove the suppressor. Input field.
