I use the inexpensive MTM wind flags as suggested to me by REVOMAN. Although they work well and wind direction(quartering) can be read easily, the one problem is that they are meant to be staked into the ground. If you have soft dirt no problem, but asphalt, gravel, or hard pan you’re SOL with these, unless you figure out a way to tripod them, but that doesn’t guarantee they won’t topple over.
So before RMAC I made these up- 1 gallon buckets filled with play sand, with a rubber electrical firewall grommet installed dead center. The MTM’s wind flag stake can easily puncture the grommet and the seal from weather maintains around the shaft of the wind flag. Easily portable
