High Power Wind Lab
wind analysis and for high power, PRS, and ELR shooters
High Power Wind Lab is an advanced visualization tool designed to help you determine sight corrections based on real-time wind conditions.
Whether you’re on or off the range, High Power Wind Lab lets you interactively explore various scenarios to gain a deeper understanding of how wind influences bullet trajectory. By adjusting wind velocity and angle, the tool not only calculates the necessary corrections but also simulates potential outcomes if the wind is misjudged. This interactive experience is essential for mastering the nuances of wind direction and speed, empowering you to make informed decisions about when to shoot and what adjustments to apply to your firearm.
In addition to its visualization capabilities, High Power Wind Lab serves as a sophisticated plotting tool for recording both shot placement and wind conditions. During your shooting session, use it to track prevailing conditions and refine your corrections based on reliable data. Afterward, review your plots to analyze your performance and learn from your experiences, ensuring continual improvement.

Getting Started
The intro screen is your starting point for all new shooting sessions. Here, you can select a Load, Target, and Distance, as well as name your session. You can also load previous sessions for review. It’s crucial to choose the correct target and distance for accurate calculations.
To select a load, distance, or target, simply click on the corresponding option. On the Load screen, you have the option to create your own custom load or generate a demo load to get started quickly.
Once you’ve made your selections, click the “Start” button at the top of the screen to begin your session.
The target screen will now appear, featuring the following elements:
- Wind Direction Dial
- Wind Flags
- Correction Scale (located at the bottom)
- Target
Wind Direction
Use the wind direction dial to select the wind’s angle. Simply touch and drag the dial to set the desired direction. When the dial points to the 12 o’clock position, the wind is blowing directly toward the targets. At the 3 o’clock position, the wind is moving from left to right across the range.
The wedge-shaped selector spans 30 degrees, with 15 degrees on either side of the arrow, representing potential errors in reading the wind direction.
As you record shots, pegs will appear around the dial’s perimeter. The length of each peg indicates wind velocity, while its position corresponds to the wind’s direction.
Dist: distance to target.
Angle: wind angle in degrees.
V: wind velocity in miles per hour.
EV: effective wind velocity in miles per hour.
Man: manual correction added to correction scale in MOA
MOA: calculated correction in MOA
Wind Flags
The wind flags are used to determine the wind’s speed (velocity), visually approximating how they would appear at various speeds. The scale ranges from 0 to 25 mph.
The wind selector is a broad red bar with a thin black line running through the center. This bar represents a 3 mph range, with ±1.5 mph on either side of the center line.
To set the wind velocity, simply drag the red selector to your desired speed.
Correction Scale
The correction scale shows the adjustments needed to compensate for wind velocity and direction. By default, it displays the calculated wind correction, but you can manually adjust it by dragging the scale left or right.
The blue bar on the scale represents the correction range for ±15 degrees of the selected wind direction, matching the width of the blue wedge on the Wind Direction gauge.
The red bar indicates the correction required for ±1.5 mph of the selected wind speed, corresponding to the width of the red bar on the Wind Flags gauge.
Target
The target serves two primary functions:
- Records shots
- Displays the potential impact range if the wind is misread
The blue bar represents ±15 degrees of the calculated correction, while the red bar shows ±1.5 mph of the calculated correction. Both bars are scaled to fit the target’s dimensions.
To adjust the calculated wind correction (also known as “doping”), you can drag the wind correction scale left or right. The bars on the target will shift accordingly based on the MOA correction you choose. To move the bar, first click the lock button to unlock the scale’s position, then drag to adjust.
Record a calls and shots
To record calls and shots, tap the screen and press either Call or Shot. Calls and Shots are recorded in pairs, but both don’t need to be entered. If you record a shot after a call, then the call and shot are stored together. If you’re confused, just play with it – it will make sense.
Configure a custom load
In order for High Power Wind Lab to correctly calculate a corrections, it needs to know a little about your load – specifically, the MOA drift for a full value (90 degree), 10 mph wind. This information can be calculated using a ballistic calculator.
From the Select Load screen, click New. Fill out the correction s and a description of your load, and click Save.
You can now select this load from the Select Load screen to use in a shooting session.
If you need to edit a load, click the Edit button the right side of the list item. To delete a load, drag a load to the left to expose a delete button.
Create variations of your load for different altitude, temperature, humidity, and barometric pressure combinations so you can see how these parameters affect wind deflection.
Frequently Asked Questions
1) Is the application legal to use during a match?
No. This app is intended to be a training aid, both on and off the range, to help develop the intuitive understanding of how conditions will affect your shots so you can make better decisions during a match.
2) With the wind pointed at 12 or 6 o'clock, +/- 15 degress shows a potential hit in the 8 ring or wider. This can't be accurate, can it?
The software is very accurate and this is, in fact, what can happen if you misjudge a fishtailing wind. You can verify this for yourself with a ballistic calculator. Set the distance to 1,000 yards, configure your load, and set the wind angle to 15 degrees and wind speed to 10 mph. Compare the MOA offset from the calculator to the blue bar on the target. If you are using the same load configuration in High Power Wind Lab, the end of the blue bar will correspond to the calculated MOA offset. If you want a precise measurement of that point, place a spotter on the target at the end of the blue line.
Troubleshooting
Is an Android version available?
Affected Platforms: Android
The Android version of the application has been pulled from the Google Play Store. At this time, it is uncertain whether a Android version of the application will be built. These types of apps are time consumer to make for little to no profit. If there is a strong enough demand for the app on Android, it will be considered.
