Designed for extreme sporting events like extreme skydiving, extreme mountain biking, extreme skateboarding and extreme bush-peeping, the SC-X210WL wireless helmet-cam lets you catch all the action while keeping both hands free to participate.
The SC-X210 is an upgrade of their old sports camcorder that cuts the wire between the helmet-cam and the camcorder. The helmet part has a fifteen-foot range from the base camcorder, so you're going to have to still carry both pieces around. Its 1GB of internal memory records up to 34 minutes of MPEG4 video, and can be expanded via SD slot.
There's also 10x optical zoom for when you really want to focus in and get 10 times as extreme. Available in September for $679.
