Whole-course preview appears first. The 2 ft source terrain and full aerial view save automatically for offline use.
Distances in yards. Carry calibrates reference flight. Total calibrates typical rollout on a flat, normal fairway. Course surfaces and slope still change rollout; launch and spin remain estimated.
Plays-like model: generalized club flight with gravity, drag, approximate lift and moist-air density. Yellow is the estimated standard-air shot; blue is the estimated corrected flight. These are visual guidance, not a measured ball or club fit. Gusts, spin and actual launch can change the result. GPS accuracy is reported separately.
