Just added this neat little gadget to my kit. Useful when you want to check the wind speed at your actual location rather than rely on the general speeds given by the various apps. It’s really small and unobtrusive and comes with a sleeve/grip in a variety of high-vis colours.
Luckily, after years of paragliding and having to assess wind at the take-off site, I can hear the wind in my ears and know what’s happening.
However, yeeeeears ago, I used to have such a anemometer … but then rarely used it.
They are really useful, but don’t forget they give you the wind speed at ground level which is usually significantly less than when you are up there. Don’t let it lull you into a false sense of security, just use it as a starting guide.
