WOO 4.0 is a simple, discrete onboard sensor that magically measures every kiteboarding jump. Tap record and the WOO automatically detects when you're on the water and in the air, calculating each jump's height, airtime, jump graph, and more.

The 4.0 sensor has been reengineered for the future of big air kiting, winging, and beyond. 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 riding while your WOO goes to work tracking every take-off, jump, and landing. There's a reason WOO is the Standard of Measurement for big air.

Record a session with WOO and you're joining a Global Kiteboarding Community that shares sessions every day on the app. Collectively the community contributes to a Kite Spot Map, Leaderboards, Activity Feed, and a shared love for the sport.

Kit includes the WOO 4.0 Sensor, USB-C Charger, Adhesive Board Mount, Replacement Bands, Prep Alcohol Pad, and WOO Sticker.
