Freefall Data Systems is studying where skydivers wear their altimeters. You will be asked to mark every place you wear an altimeter on the jumps you normally do. It takes about 3 minutes.

Taking part is voluntary; you can skip any question or stop at any time. The survey is anonymous: we do not collect names, emails, USPA numbers or IP addresses. Results are reported only in aggregate. There are no foreseeable risks and there is no direct benefit to you.

You must be 18 or older and a skydiver (any experience level). Questions: casey@freefalldatasystems.com.

A response has already been sent from this browser. If that was you, please don’t take the survey again; if you are someone else, go ahead.

Mark every place you wear an altimeter of any kind (analog, digital, audible, peripheral LED, etc.) on the jumps you normally do. If you wear one somewhere only for certain jumps, mark it as well.

Your answers are in. Results will appear in the Research section once the full run is complete.
