Knowing the wind speed and direction is vital for paragliding and hang-gliding. WindTalkers give you current wind speed and direction along with a history which helps visualise wind and weather trends. In addition to observing temperature, humidity and brightness variations helps predict thermal updraft velocity. For example significant changes in brightness and temperature will indicate well defined clouds. Knowing the WindTalker altitude, humidity and temperature, the dew point can be calculated and thus the theoretical height of the cloud base.

Note much effort goes into ensuring the wind and weather information supplied is completely accurate, however there is no guarantee that it is correct. Paraglider and hang-glider pilots should use their own judgement when deciding if it is safe to fly.
