Introduction
The Wind Zero App now includes a ballistic calculator to estimate bullet wind drift and drop. It uses advanced ballistics computations, including optional factors like the Coriolis effect, aerodynamic jump, and spin drift, to return detailed trajectory information. It also includes the capability to model different wind zones and the ability to assign a wind meter to each.
| Distance | Wind Zero Location |
| 0 | Meter 1 |
| 300 | Meter 2 |
| 600 | Meter 3 |
Wind Drift
The Wind Drift page displays the current real-time wind drift based on the wind meter readings. The values displayed are the current calculated drift as well as the maximum and minimum values during the previous user-defined period (Bracket). The elevation and velocity at target are also displayed. The values are shown in numeric values as well as a chart with the current value shown as a diamond and the min snf msx values shown as a bracket.
- Profile: Select the Profile number (1 – 10). The name of the profile will be displayed
- Target: Select the Target number (1-20). The name of the target will be displayed.
- Range: Target range (yards).
- Angle: Angle of target from Wind Zero direction. Positive right, Negative left
- Inclination: Target inclination angle (degrees). Positive for up, negative for down.
