ThE SELL: An adventure-ready helmet cam with new add-ons. THE TEST: GoPros have better image-stabilization tech than any other helmet cam. But until now, you couldn’t see what you were filming. A new plug-in LCD screen ($100) fixes that problem, while a Wi-Fi kit ($100) let us stream real-time footage from our buddy’s kayak on an onshore phone and then upload it to the Web. THE VERDICT: The same great Hero2 and then some.
Brand: GoPro $300
