Any plain old Kestrel wind meter or any other is fine for you at bench. The more advanced ones can blue tooth wind speeds back to shooter or smart scope, at say 25 yard intervals on way to targets.
You might as well learn to read the signs of nature around you, use your senses along with the wind flags. When you see every flag from bench to 100 at a 90* angle, and your skin tells you what that feels like, you begin to learn by putting the data with the visual info flags are providing.
Besides knowing what mph winds it takes to move a trees brances with, or without leaves, leaves & grass alone, pollen or anything else being affected by wind and gravity.
I shoot prone mostly by choice for now. I happen to know that grass midges & mosquitoes will bother the heck out of me, up to I believe 3 or 5 mph. Somewhere in between there, they can’t hover & annoy me while I’m at their ground level.
Birds will always take off into the wind. Never against it. Facing it gives their wings lift.
I use to set up a burn barrel for leaves, the smoke shows everything about the wind around it.
