A:Answer Too late for the poster, but to make sure no one else reads this and gets any ideas. You would _not_ take this skydiving. If you are doing a tandem, you don't bring a camera period - doing so could endanger the life of you and the tandem pilot. If you skydive for yourself, just ask your instructors on what would be an appropriate mount (And seeing that you need 200 skydives before using a camera, that would be far in the future)
