The Gadget: A small waterproof sports camera with mounts for handlebars, helmets, chests, surfboards, snowboards/skis, cars — almost anything. This cam has a 170-degree wide-angle lens. And it's cheap and amazing.
The Price: $200
The Verdict:This is the best sports cam I've ever used. The various mounts allow it to be strapped to a helmet, a chest, a rollbar in a car, or on the glass or metal of an auto's flat surfaces via suction cup. There's a plug mount and 3M mount for surfboards, or a 3M mount for ski/snowboards. There are even bicycle mounts for facing rear and forward. And I could see the chest mount being applicable to almost any sport, from martial arts, to kayaking, to hockey. (The mounts are sold separately.) It's cheap enough you shouldn't worry about it too much either, at $200. Although I did still worry about it a little bit: The mounts worked, but I've popped the 3M mount off a snowboard on a hard day of riding, and since then have depended on the large suction cup and a tether for safety.
It's housed in a tough plastic case, that locks tight, which makes it waterproof enough to submerge it 100 feet. The camera takes SD cards, and between the 2xAAA battery life and 2GB of storage, you end up with about 1 hour of footage and life in the cold. Buy rechargeable batteries. (The camera is noted to have shorter battery life in colder weather and using lithium or NiMH you can get 2-3 hours in regular climates.) Video quality comes in at 512x384, and works well on cloudy days, but in bright environments it shines. The Hero also has a 5MP still mode which can record stills continuously at 2 or 5 second intervals. (I've included some samples in the gallery.)
