TrueCourse is a GPS-based survey, checking, and course setup tool for waterski course layouts. Designed for clubs, course owners, coaches, and serious skiers, TrueCourse helps capture course buoy positions, compare them against standard course geometry, and assist with setting out new slalom course layouts. TrueCourse includes tools for both checking existing courses and installing new course layouts. In Survey mode, users can capture course buoy positions, review the measured layout, and identify buoys that may need adjustment. In Install Course mode, users can capture a starting gate and direction point, then generate exact slalom buoy target positions based on official course dimensions. TrueCourse is designed to be simple to use on the water. Select the buoy position, capture the survey or install point, and review clear position guidance. Audible confirmation and simple controls help make the process easier while working around the course. TrueCourse requires a compatible Skiable RTK Unit for high-accuracy positioning. The app is designed to work with Skiable’s own RTK hardware system and is not intended to connect directly to standalone UM980 boards or unsupported third-party GNSS receivers. For setup, compatibility, and hardware availability, please contact Skiable before purchasing or using the app. Key Features • Capture survey points for waterski course buoys • Survey and check existing slalom course layouts • Install new slalom course layouts using exact generated buoy targets • Capture an entry gate and direction point to create a full course layout • Check slalom entry gates, exit gates, pre-gates, boat guides, and all six turn buoys • Simple Set, Clear, and guided install controls • Audible confirmation when a point is captured • Clear visual feedback for buoy position checking and installation guidance • Export course survey results • Designed for use with a compatible Skiable RTK Unit • Useful for course setup, maintenance, and training preparation • Built for Apple devices TrueCourse is intended as a course checking, setup, and installation aid.
