GoPro HD Hero review and helmet cam face-off

What’s this, another tiny, high-definition camera to strap onto your person before doing something wild and crazy? Yes, it’s the latest pixel-pushing contender for high-def helmetcam supremacy, the GoPro HD Hero; a little gray box in a waterproof case that can record 1080p at 30fps, 720p at 60, and comes with a selection of mounts that will enable the thing to hang on to just about whatever you want to sling it from — but at $299 you might not feel particularly inclined to put it in harm’s way. Worth the risk, and how does it compare to the competition and its predecessors? Read on for the full analysis, and of course plenty of gratuitous high definition footage.
