WOO 4.0 The New Standard for Big Air Kiteboarding A ruggedized housing now surrounds a more powerful processor and extremely precise sensor. Wireless charging, 24+ hour battery life, updated Bluetooth and many more important improvements mean that you can focus on kiteboarding while your WOO goes to work tracking every take-off, jump, and landing. Ten years in the making, WOO 4.0 builds on everything weve learned from a global community pushing the limits of kiteboarding. Our original intent is unchanged - a simple, discrete onboard sensor that magically captures every kiteboarding jump. But inside and out, the WOO 4.0 has been reengineered for the future of the sport.

The WOO 4.0 is designed for the Classic WOO Mount, included in the package and available as an accessory. This mount is suggested for all WOOs due to its slim profile and lower stack height on the board. Woo 4.0 Package Includes: Woo 4.0 Woo Mount Woo 4.0 Charger
