Torque Jet Boards is looking for resellers and investors on their website. Check out their questionnaires, if you are interested.
The Mongrel & Xtream Surfboards come with an app, where you setup your board for beginners or pros. It checks the speed, the distance and your leaderboard position.
The leaderboard position is related to the JT Leader Board Tour. It compares the riders all over the world and the winner will get an electric surfboard. In order to participate you need to setup a special course, which will be the same for all riders in the world and tracked by GPS.
The course needs to be setup by a local reseller or partner. Torque developers have manufactured buoys that will be positioned in the water to outline a racetrack. The buoys and the boards are GPS implanted with the most advanced GPS technology that is accurate to within a metre.
