How To Read Mirage and Estimate Wind Speed Using a Spotting Scope

Mirage, on the other hand, is one of those things that may make even the most expensive and finest spotting scope worthless. 

A good spotting scope, on the other hand, may help you strike your target dead on. You need clarity, and high-quality scopes have the glass to provide it.

But, when mirage is destroying your objective, how can you compensate? Squint no longer if you’re interested in long-range shooting, such as competitive bench-rest, or if you’re attempting to understand the mirage phenomena.

We’ve put up a tutorial to help you get the most out of mirage – wind speed reading. First and foremost, let’s get the foundation in order.

What is Mirage?

Let’s simply put it out without getting too technical about cold and warm air, refracting light, and the gradient index of perspective. 

Mirage is the swaying, moving wall of air that distorts your picture and causes it to leap, shift, and move out of position on a regular basis. 

Because you can’t exactly get your crosshairs dead-on, it may be the misery of your hunt or competition shot.

However, if you can utilize mirage to assess wind speed and direction, it may be huge assistance in ensuring that your changes are as precise as possible.

Why is Wind Relevant?

Mirage will be seen whether there is a little breeze, a strong breeze, or no wind at all. 

The pattern in which the mirage moves will indicate if the wind will be a problem in terms of precision, and whether you should adjust, wait for the wind to change, or call it a day.

The wind impacts your intended bullet impact, as many competition shooters, long-range hunters, and professional snipers know. 

It has the ability to skew your shot or cause it to miss completely, and it will have repercussions, particularly if the initial shot is crucial. 

Let’s look at how you may improve your chances of getting a clear, precise shot when you have mirage on your range.

Tips to Using Mirage to Read Wind Speed

Use a Spotting Scope

The Riflescopes, on the other hand, are far less powerful than a spotting scope. Although the Spotters usually select where rifle scopes and binoculars end in magnification. 

They get the advantage of being able to notice finer details from a greater distance. A spotting scope, on the other hand, can see what the mirage is happening at the target when it comes to mirage. 

When a mirage is present, you don’t need to overshoot your attention beyond the target. This may drastically alter your view, perspective, and proper distance. 

Focus on the objective and then dial back down to anywhere between halfway and 3/4 of the way to the target is a decent rule of thumb.

Furthermore, an optic that can rotate and shift an image is required to optimize your effectiveness in interpreting real wind direction using a spotting scope. 

Simply stated, a spotting scope is capable of doing this, while a rifle scope is not.

Ditch the Anemometer

So, if it were that simple to read wind velocity and how it affects your shot, we’d all be carrying anemometers around all the time. 

There’s a reason why most of us aren’t. Anemometers can only measure wind speed in one place: where you’re standing. 

The problem is that the wind speed at your aim point and in the centre ground may differ from where you will be firing. 

This particular interpretation has a number of drawbacks. Instead, learn to read mirage and perform some hard lifting.

Reduce magnification

Okay, the greatest part about spotting scopes is that they are very powerful. However, this may reveal a significant problem, and clarity is lost. 

Because your picture is enlarged, you must sacrifice clarity. This is especially true if a mirage is present. 

To interpret mirage, you’ll need a scope with a magnification of approximately 25X to keep your picture near enough, unbroken, and transparent.

 If you’re using a high-powered rifle scope, reduce the magnification to approximately 10-12X instead of 16X to avoid the effects of mirage. 

This is where high-quality spotting scopes with premium glass outperform cheap scopes

The spotting scope with the greatest drink will always be the best spotting scope for reading mirage.

Determine Mirage Density

The stronger the mirage, the more scope adjustments would be required. Light, moderate, and rich mirage are the three types of mirage.

Determine Wind Direction

Determine Wind Direction

The way a mirage moves may reveal a lot about wind speed and direction. Examine a flag on the range, a plastic bag stuck on a tree branch, the waving grass blades, or the shifting canopy of trees. 

Well, any of these things, particularly a flag on the range, may tell you wind direction, but unless you’re out on the plains of the Southwest, you’re unlikely to see much except leafless plants.

However, using the terrain around you to predict wind impacts might be helpful, and you may also rely on mirage. 

However, although you may be aware of the direction, for example, that it is coming from the East or that wind is blowing from left to right, it is not the only element affecting your shot. 

You must be aware of the four distinct types of mirage that may assist you in determining where the image’s true objective is.

Determine Mirage Classification

Knowing the kind of mirage you’re dealing with, on the other hand, may help you determine how far away the picture is from the object. 

You’re undoubtedly aware that there’s a left-to-right wind blowing right now, and the mirage is at a 30-degree angle, so you’re probably not as far away as you thought. 

You may study your target and how much you want to hold over if you can inspect your mirage class.

  • Slow Mirage
  • Medium Mirage
  • Fast Mirage
  • Boiling Lateral Mirage

Record Everything

To be a champion, you must be able to see downrange and understand how the variables from where you are to your goal will affect the outcome on paper. 

You may not need any of this if you’re aiming to stay under 2 MOA. However, if you want to be surgically accurate and better than 1/2 MOA, you’ll need to conduct some research on mirage.

Keep track of your target distances, time of day, weapon and ammunition used, weather conditions, scores, and anything else related to mirages. You may even join a long-distance team and observe match sessions.

Final verdict:

How mirage impacts shooting has a lot of math and fancy scientific concepts. However, you may always save time by photographing when mirage is less of a problem, such as around dawn or when the weather is mostly cloudy.

But if you’re not the sort to allow a few mirages get in the way of your trigger-happy mentality, go out there and watch the wind. 

It only becomes as significant as you make it. Even if Mirage insists on hanging around, practise and record-keeping may help you become a precise shooter.

So, in this post, we covered the basics of reading, merging and calculating wind speed using a spotting scope.
