The best on the PGA Tour Averages 31 feet from the flag on approach shots and the worst is 41 feet. So where does that leave us amateurs? Probably pretty far from the hole. It’s tough to walk around the hole from the other side and find your marker on the green so you can see the line. These markers have a stand up flag when you are far from the hole so you can easily locate your spot. In closer? No problem, just lay the flag flat. The Stand Up Flag Green Ball Marker measures just 1.25″ across and comes with sparkly material that really pops in sunlight. Check out all the pics.
