The latest version of the WOO device comes with a durable casing that provides protection to a more advanced processor and an exceptionally accurate sensor. With wireless charging, a battery that lasts for over 24 hours, upgraded Bluetooth, and other significant enhancements, you can now concentrate on your kiteboarding activity while the WOO tracks and records every take-off, jump, and landing.

Developed over the course of a decade, WOO 4.0 utilizes insights gained from a worldwide community that continually tests the boundaries of kiteboarding. Despite its original purpose remaining unchanged - to create an uncomplicated, unobtrusive onboard sensor that effortlessly records every kiteboarding leap - the WOO 4.0 has undergone a complete overhaul, both internally and externally, to meet the needs of the sport's future.
Pair your WOO with a smartwatch to add a dynamic display for your kite stats, including the height of every jump right after you land. Game on!

Recently upgraded my old WOO 2.0 to the WOO 4.0, via the upgrade program offered at Worthing Watersports. First run out recently with live stats connected on the iwatch and the setup worked faultlessly. Still had loads of battery life for another few sessions. The 2.0 had a 1 (maybe) 2 session battery life but this 4.0 only used around 15%. Wireless charging is far simpler and the whole product and its setup are a big improvement. Excellent service from Worthing Watersports - Great price, communication and included speedy delivery. It’s 5 stars all round from me!
