For your $380 you get not one but two Tachyon XC helmet cameras, which individually go for $180. Each packs a somewhat disappointing VGA (640 x 480) image sensor behind a 90-degree wide-angle lens, all wrapped in a durable plastic case that we have no doubt would survive a harder tumble than you. On top is a tiny, one-inch LCD that gives you a quick readout on storage space remaining, battery life, what quality mode you're in, and is also used to make failed attempts to set the internal clock -- not a fun task, believe you us.

Three buttons live beneath the screen, the biggest being the most important: Start/Stop. This should be preferably be pressed sometime before the action begins (the important "hold my beer" phase) and then again sometime after it ends (right around when someone mentions calling an ambulance). Smaller power and menu buttons sit beneath that, all three of which require a disconcerting amount of pressure to activate; you really need to push hard to get anything to register, so thank goodness a tiny remote is included. It's much easier to press and is more or less necessary for filming in 3D (we'll explain why later), but sadly can't turn the cameras either on or off, neither can you strap it on your wrist, and since it has a range of no more than a foot in sunlight, well, it's not as useful as you might hope.
