"The GoPro HD Camera is very capable of picking up decent audio of rip roaring engines and screeching tires, but actual 'wind rumbling' can make or break your audio. To get the best possible audio when your GoPro is exposed to high wind conditions, we put the latest Windscreen from Micover to the test. This Furry little backing mounts to the stock non-waterproof cover of your GoPro HD with a strong adhesive. There's a thick layer of acoustically transparent fabric under the same Furry material found on other Micover products. The results to eliminate wind rumbling at super close range are like night and day. We feel this is a must have for any GoPro owner." -OliviaTech
