Want to catch every frame of your next extreme sports wipeout in all of its grotesque glory? GoPro knows where you're coming from, and has updated its line of high definition helmet cams to help you capture every bone-breaking moment. The HD Hero2 competitively boasts that it's twice as powerful its 2009 predecessor, the original HD Hero. The new helmet cam promises to capture 1080p 16:9 footage from atop your sweaty noggin at both narrow (90-degree), wide (170-degree) and medium (127-degree) angles, and can snap up to ten 11 megapixel photos per second.
