This past winter I saw a lot of people hitting the slopes with helmet cameras. Now it seems that helmet cameras are appearing everywhere, from motorcross to hangliding to surfing, and now in the show jumping arena. The camera that seems to be the most popular is the GoPro HD Helmet Hero. The Hero can record up to 2.5 hours on a single charge and can fit 9 hours of footage on a single 32GB card. Additionally "this digital action sports helmet cam also shoots 5MP still photographs at 2/5/10/30 or 60 second intervals. Press the shutter button once and record up to 2.5 hours of poster-print quality POV photos of you and your friends’ most memorable moments."
The HD Helmet Hero costs $299.99 and is available at the GoPro website as well as Amazon.com.
