It really doesn’t matter what sort of gadget you are looking at or talking about, if it is rugged, you will pay a premium. There are a number of sports camcorders on the market today that are rugged and designed to mount to all manner of things for recording action sports.
A lot of those cameras have to be inside waterproof housings to be rugged though. The new POV.HD camcorder from V.I.O has surfaced for pre-order and it needs no plastic housing to be rugged. The camera itself is water resistant to 1 meter for 30 minutes and it has an environmental rating of IP67.
The camera can mount to helmets, goggles, and other places with included mounts and records video to SD cards. The thing also has a wireless remote that can stop and start recording as well as tag video. It ships with a handheld device with an LED screen on it for viewing video in the field too. You can pre-order now for $599.95.
