Garmin Tactix Delta Owner's Manual page 39

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. The
actual windage to apply for the shot should fall in this range.
Target 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 Properties
Ballistic Coefficient: The manufacturer's ballistic coefficient for your bullet. Input field.
