If you are a really kitesurf maniac, you might want to get a Shadowbox. Using gyroscope, GPS, sensors, and a lot of other technology, you can track the board’s exact position, horizontal and vertical angle down to milliseconds.

The Shadow box gives a complete visualization of your moves on the water and the graph shows a kite board flying around the screen.
Besides this it allows to measure both the height, g-force, speed, acceleration, hung hours, rotations and also replay the ride from any angle with the 3d viewing program or export to Google Earth.

Check the movie of Shawn Richman using a ShadowBox at the AWSI expo in Hood River and enjoy the subtle world of technology.

The price of the Shadow Box is around USD $ 499.00 and can be purchased online at: Shopatron.com

We hadn’t the chance to test it, but from what we read and saw we can say this:
The best: Finally you can track all your sessions and check how high you really jump
The worst: Price; You might be disappointed how high you jump
