LEARNING TO READ MIRAGE The magic of mirage. When the wind comes from different directions or points around the clock, it has a greater or lesser effect on where the bullet hits the target. To see mirage, use a good spotting scope, focus on the target the back off the focus about a 16th of a turn towards you (BACK FOCUS), you want to read the wind mirage at this distance from the target. When the wind picks up the mirage angle increases causing the mirage to lay down at a certain angle, giving you not only speed but direction the wind is coming from, by the tightness of the heat waves. Using the app: Hold the Phone to the Angle of the Mirage, then-Push the button that looks like the mirage you are seeing - like the one below, it will lock the wind speed until you push it again to unlock. This represents 75% mirage of a 5 MPH angle; this app will take a full value wind and calculate corrected cosine value based on Mirage velocity or direction it is coming from 3 Buttons on this app: • Full Value Large Waves 100% Value • Chatter 75% Value • Diamonds 50% Vale of the angle USING RAIN ANGLE Using Rain angle is easy; look at the rain angle in your spotting scope like you would with Mirage, hold the phone at the angle you see it. Rain can be determined by 2 types for this app • Normal Rain - you can see the target and make it out fairly clear, this is what the app was designed for. • Light Rain or Mist - you can see the target clearly, rain is very light in Mass. • Heavy Rain - target is blurry and hard to see, in that case you might hit a raindrop during bullet flight and this app does not work for that heavy mass of rain. Hold the phone at the angle the rain is falling, then hit the Full rain button for normal rain and that is the wind speed showing. Hit the the button again to unlock. Do the same for the Light Rain button. ## Key features - Mirage analysis for wind speed and direction - Rain angle interpretation for wind calculation - Multiple wind value buttons (100%, 75%, 50%) - Supports normal, light, and heavy rain conditions - Calculates corrected cosine values based on wind conditions ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/external-ballistics-pro/id1464839728/reviews.md ### 1/5 — Does not work with iPod touch *2021-12-24, version 1.2.0* The app doesn’t detect positional information on iPod touch. It registers “no wind” when you align it with mirage or rain angle. ### 5/5 — Making long range hunting/ shooting easy!! *2019-08-29, version 1.2.0* Met James last year at Dallas Safari Convention and we spoke briefly. I was intrigued by his knowledge, so I started following Barbour creek and being a long ranger hunter and beginner PRS shooting any bit of info I could soak up I did.. once that App released I have upgraded spotters and have been focusing on strictly mirage instead of what the ole kestrel had to say. I am now ranked nationally and has led me two wins and 2 top 3 finishes in major prs matches. Thank you Barbour creek and James, you guys knocked it out of the park with this app, and continue to strive for excellence. I owe a lot of my success in prs to your wind knowledge. If you don’t have this app your missing out.. ### 5/5 — Mirage Simplified *2019-06-27, version 1.0* Make the first shot count! I don’t get a chance to shoot long range as often as I’d like, which means I don’t always remember what call to make when I’m looking at mirage through my spotting scope or scope; this app makes it easy to make your wind call using mirage or rain angle. Well done, Barbour Creek! ### 5/5 — Effective *2019-06-22, version 1.0* Makes your wind calls much more precise and effective. When I use this with my ABS app I know that I’m hitting bullseye on the first round. ## Frequently asked questions about External Ballistics Pro ### What is External Ballistics Pro used for?
