This new WOO device for tracking your jump height for kitesurfing/kiteboarding.
My rough and ready review and testing is not perfect, but hopefully its useful for anyone considering buying one of these.
Its called the WOO KITEBOARDING PERFORMANCE TRACKER.
I had my doubts about its ability to gauge your height from the inertial recorders, but it looks like its not to far off.
Watch the test till the end to see more.
