Who made it
It started on a napkin.
Robert and Stacy were teaching at the same range. One rainy day nobody could get out on the grass, so they got talking about the thing that beat them both: getting students to stop coming over the top.
Stacy drew the first one on a napkin. Eight cardboard prototypes later, Robert was still hauling a cutout the size of a car door to every lesson. Then Stacy pulled off the interstate, bought a fold-up car sunshade, and cut the circle out of it. That is why The Golf Clock twists down and fits in your bag.
