I use flags from Rick Graham and windicators I made myself.
But just about any windflag commercially available is going to get the job done.
The secret isn't one guys flag versus another, it's you being able to read yours.
I've been using the same set for 3 years now
Everything is about angle and velocity.
Figuring out the wind is from the left or right is easy.
Recognizing that wind from the left is from 10:00, instead of 8:00 is critical.
I think every shooter has their favorite wind,
Mine is from the right, from 1:00-2:00, or 4:00-5:00
But every day is different and you need to find out what the predominant condition is that day.
I use my own homemade sail tails and windicators to help with velocity.
My tails are cut from 3/4 oz. ripstop nylon, 1.25 wide, and 24 inches long.
They react good in lighter conditions, but I doubt nowhere close to Richard's plastic bags.
What I like most about the nylon is it has a little curl to it that keeps them rigid lengthwise,
letting the entire tail raise and fall with the wind.
I know it works for other guys, but I have a hard time with surveyors tape and such that
will typically float and flutter around.
My windicators are just simple 180 degree pivots with a 6" length of that round foam
tube toy stuff made for swimming pools to catch the wind. I think they're called FunNoodles and were
a $1 for a 6' length at WallyWorld and come in a variety of colors.
Most important is to look for the windy days to go and practice.
The only way to learn to shoot in the wind is to shoot in the wind.
Hold on the dot, look for a readable condition, and pull the trigger.
Note where the shot went. Calculate the holdoff for that condition.
Load another bullet, set your holdoff for that readable condition and wait.
Watch your flags and when they look right, pull the trigger.
A good habit that I got into is shooting heads up.
Once I set my holdoff for a condition, I typically don't look through the
scope again until after the shot is gone. Unless I need to readjust my holdoff
due to a condition change, I don't see a need to look through the scope again.
The flags are where everything is happening and I read too many times that
someone missed a shot because they missed a condition.
My assumption is they saw something in the flags that changed by the time
they looked back through their scope and pulled the trigger.
Once again, unless you're gonna change your holdoff, why look through the
scope again.
The key is practice, practice, practice. Your brain needs a chance to see where
the bullet goes in different conditions. Every shot needs to be taken with a purpose
and intent to learn something on that shot. You can't be afraid to miss a shot if that
shot is going to provide insight on the following shots. But, that's what sighters are for.
You will always have the unexpected, unexplained shot, but as you gain experience with
your equipment and your wind skills improve, you'll get to a point where you can
predict more than not where the shot is going to go.
