Review of the THEIA II Smartwatch for Windfoiling

We are a team of sports enthusiasts, particularly those who love board sports. Windfoiling is an activity that offers an unparalleled experience on the water—the sensation of flying, of losing contact with the water. We’ve also verified the accuracy of GPS data in the Geneva harbor on Lake Geneva. As for equipment, we use a Tabou Fifty board and are very satisfied with it. About the sail, you’ll need about 1 m² less than with a traditional windsurf board. It’s best to place your front foot in the front footstrap before planing. It’s also possible to do it afterward, but it’s trickier because the board is sensitive to movement… Equipped with a 1050 cm² wing and a 7.50 m² sail, with a few knots of wind (around 12 knots) and some pumping, the foil lifts you out of the water (knowing that I my weight is around 79 kilos. The speed then stabilizes at around 17.5 knots. You can convert speed from km/h to knots using the AIRN CONNECT app.
