That’s complete with 20-60X zoom eyepiece.

You can get the Vortex 20-60圆0mm Diamondback angled spotting scope for just $399.99 from Midsouth. You don’t need to spend big bucks for an effective spotting scope to view mirage. Here’s another tip - the boil can predict when a “fishtail” wind is about to change, a boil precedes a shift. And that’s a quick and accurate means to determine wind direction, by the way, move the scope until you see the boil and note the scope body angle. The thing is that mirage shows changes, increases or decreases, and also direction shifts, really well.Ī couple more things about mirage flow: when mirage “boils,” that is appears to rise straight up, either there’s no wind or the scope is dead in-line with wind direction. Mirage flows just like water and the currents can be read with respect to wind speed as well, but it’s not clearly accurate beyond maybe a 15 mph speed. For 600 yards I focus my scope about halfway to the target. Mirage (heat waves) is always present but you’ll need a scope to read it. There are multiple resources that give clues or evidence of wind direction and strength: wind flags, observation of grass and trees, and mirage.Īlmost always I use mirage as my leading indicator.

In the photo below e you can see 11-time National High Power Champion David Tubb using a spotting scope set up for his left eye.ĭavid Tubb sets up his spotting scope so he can easily see through it with his LEFT eye, without shifting his head and body position. That gets the shooter back on the trigger with the least chance of missing another change. With well-designed stand, the scope can be set it up where you can see the wind with the left eye and see the sight with the right without anything more than a visual focus shift. Most good shooters use mirage as their leading indicator to spot changes in the wind. However, you can still order his books from Midsouth and read his articles in the Midsouth Blog.
