GoPro makes my favourite sports cams. The 1080p cameras are getting optional LCD screens and battery packs, but the real news is this double camera housing kit that syncs the two cameras for 3D. Love it.
I saw a video. It looks great. I can't imagine a future where we're not doing all our sports videos in 3D. This kit is a great start for someone who already has a set of GoPro cameras, but I can't help but think this is an interim step.
The camera kit isn't small, and you do need to already own the top of the line cameras - two of them. And you need SD cards in both and to charge both and to buy this kit. And then to use software to knit the video together. The result is amazing, but the package is bulky and one day I hope GoPro makes a single camera that can handle 3D without needing two of everything to do it.
Until then, I'm going to be using this set up in the surf and snow.
The battery pack extends battery life to five hours, and the LCD cuts battery life by about 30-40 per cent if you're using it the entire time. Pretty reasonable, but both seem only necessary for those recording long adventures.
