You might think the POV / action sports camera world has been a bit of a two horse race recently. That could all change, however, now ION has muscled into the scene with its Air Pro HD sports camera. The firms dabbled with handy cameras before, but now its dipping a well armored toe into the helmet-cam market. Needless to say, that means its rugged, waterproof, and built to eat dirt — or at least capture the moments when you do.Your action is scooped-up in full 1080p HD, and theres a 5-megapixel stills option for when you want to frame that killer jump for static posterity. The lens is a 170-degree wide-angle affair, you can change the FOV if you wish, but its definitely enough to grab all the action. Theres also no display on the device itself, but theres a reason for that: operating the Air Pro is a ridiculously straightforward task. With just one click youre recording, even if switched off. The two controls on top are all you need to get the essential jobs done with this device, a button for switching it on and off and taking stills and the sliding record switch — this set-up also means you can physically feel if its recording, even when you cant see it.
