Looks like an F Class Tool,
Does it do Mils, what do you do when you are not using flags, how does this translate to using the MPH of the Rifle System to calculate the calls, it appears it can help you monitor the wind vs recording the data and doing it manually but it seems pretty old school, like circa 1978 in your hand.
New more details
Great questions! Thank you for asking.
- Currently it only does MOA, but Mils and metric distances are on the product roadmap and will be coming shortly.
- if you don't have flags, you'll either need to use other wind indicators or an anemometer and enter the wind velocity. The flags section of the screen is a slider control for entering wind from 0 to 20 MPH, the velocity is shown just above the flags so you can easily enter the value from your kestrel or your best guess
- the MPH's you see on the screenshot is the wind velocity, not the bullet velocity
The application uses ballistics for your ammunition and supports multiple load profiles.
The app works by allowing the shooter to enter the wind velocity (flags control) and the wind angle (clock dial) and it calculates the absolute correction (green dot on scale at bottom) as well as the correction +/- 15 degrees of the input direction (blue dots) and +/- 1.5 MPH of the input wind velocity (red dots). This information represents a "bracket" to shoot within. It also shows you those you what the size of that bracket is on the target, to scale.
The application comes with a library of target rifle and f-class mid and long range targets. A feature we're considering adding are IPSC steel targets in standard dimensions.
The purpose of the app is to help shooters learn wind reading by showing interactively how angle and velocity interplay by interactively changing the parameters. Then as you shoot and plot shots, it also records the wind angle and velocity so you can see how your conditions develop over time, as well as help you identify predominant conditions. Another feature in the works is to output the actual correction needed if the shot lands left or right of center.
