Fierce Vinyl appears to be kaput.

And just to provide links to the businesses in the other images just since you used their logo’s…

I don’t use white shields because they reflect sun rays back into the objective end, creating more mirage. I cut pieces of vinyl siding to a width of 2″ and paint them dull black.

Interesting that it matters not what people do to try and be assistive in the shooting world there will always be someone that has a negative angle on things…
The company selling these may not actually have much to do with shooting but the person doing them has grown up on various shooting ranges and listened to many a conversation from their father “SPEEDY” and other esteemed shooters to have picked up on at least some great tips…Sure wish he was part of my family…

I can also add that should a person have thermal imaging gear (as has also been done) they will see there is quite some representation of the images (and yes…drawn as in indicative reference and not to scale and all the other stuff basically to try and keep the image as simplistic as possible) so take from it what you will.

If you have a cheaper way of doing things that gives you satisfaction then have at it…I found this much easier for me to get a professional finish…even all the way from Australia each one cost me less than $30…dirt cheap…

Oh…And the person that did draw it (again just as a visual representation tool) is now approaching his mid 40’s and has been a Target Rifle shooter for almost 20 years…Still doesnt know anywhere near as much as most other folk apparently but enjoying it…

The purported heat flow “logic” escapes me.

It appears that on the left and center the mirage/heat “flow” is in front of the scope and the right image it is at or behind the objective. Why would the right image not converge earlier – or conversely, why would the left image not tend to go more vertical after clearing the edge of the flat shield?

Also, why would the right image not have a below-shield path more similarly straight up and then curve around the shield.

My take is that there is ZERO science around this “statement” and what is shown is, IMHO, quite unlikely to be an accurate representation of actual heat flow characteristics.

Finally, if you look at their site, the company is selling graphics applied on various surfaces – about 98% of the site content has zero to do with shooting.

The mirage shield I made for my F-Class rifle cost about 50 cents and I’m sure I could have done it cheaper. I bought a 4″ piece of aluminum roof flashing and cut down the middle with a pair of scissors. I bent a curve in the middle, the same as the ones advertised and it rolls up to go in a 2×3″ diameter cardboard tube. Before I get accused of being too cheap, this is used on a $3K (before scope)custom rifle. It works great.

These will probably sell like crazy to those who have more money than sense. Then there are the rest of us that think spending 1/50th of the money for the same result is a better idea.

Ryan: Good tip. On the Daily Bulletin we have published stories on how to make your own Mirage Shield, as you did. But we will say, for those who want a color GRAPHIC on their shield — to advertise a team, club, or business — $21.99 is a very reasonable price.

We can’t say this diagram is based on exhaustive scientific testing (and we think the flow patterns are exaggerated for effect), but it does illustrate how airflow can be altered by shield shape.

Did you test it?
