I think this is the best windsock out on the market right now. For only $20 it is a good deal, highly visible, and is shows the lightest of wind. It’s so important to know the wind direction and this massive 15foot sock/snake shows the faintest of wind. You can also set it up in such a way that it can lay on the ground so you will know which way the wind was blowing before. Oh, and it’s made in the USA!
Another essential piece of kit for your hang gliding rig. These radios have done pretty good for me over the past 3 years. For the price you can’t beat it. I have been able to connect to the repeaters in my area and during Hurricane Harvey I was able to reach first responders on boats. They can be upgraded with an antenna and lots of accessories.
