Being new to skydiving, but having some experience with other activities that require helmet cameras to be video'd, I have noticed a disparity in the approaches. Namely, skydivers tend to mount the whole camcorder on their helmets, where-as other sports such as mountainbiking, motorcycling and snowboarding use small, 'lipstick' cameras (Sony makes quite a few, they are really just CCD cameras that output a analog video signal, normally sealed in a waterproof housing) on the helmets, with small cables for video feed and power leading to a practical place for a camcorder, usually a backpack etc. . This kind of setup would seem very suited to sky-diving for a couple of reasons: -the cameras are really small, therefore they can be mounted to catch very little wind and be almost snag-proof -the bulkier and heavier (than the small camera) camcorder can be placed elsewhere on the skydiver, creating less strain on neck and affecting balance less -the mic can be placed anywhere (i.e. in-helmet for commentary if you have a full-face that seals real well) -with DV and a good camera, they don't seem to mean any loss in picture quality and they do have a variety of available lenses. I can't see any drawbacks for these cameras in a skydiving application and they're not even very expensive (about $120-$200). So my question: why have I not seen (or read, or heard about) any skydivers using these? please solve this mystery for me, thanks
