tee signs
Tee Signs need to be placed near the back of the tee to avoid a nasty ricochet. A golf ball can take off at 150 mph, many times in the wrong direction. Test material with a golf ball & slingshot to see how it holds up.
Golfers who hit poor tee shots sometimes take it out on the tee sign which is why many are made of stone.
The decimal point seems to be the most important on the z axis... x & y not so much....
