Here's one handy tool for people who want to surf and sail but need the wind to do so. Sometimes, weather predictions aren't as accurate, and can change at any time, so having your very own weather prediction tool can be handy if you're a surfer, or sailor. Because you need wind for those kind of things. Shaka's anemometer accessory will turn your iPhone into a handheld weather prediction tool!
The $60 wind meter will attach to your phone's headphone jack, and feeds it data about wind speed, direction and the temperature. You can compare today's measurements with past readings and share them with fellow surfers via various social networks. Pretty handy, no?
