Just wanted to say thanks for the education on this. I have been playing golf for many years and “thought” I had been doing right by the course repairing mine and many other ball marks. I am embarrassed to admit I had been repairing marks the wrong way all along.(It’s all I have ever encountered) I will make sure to spread the word to my playing buddies on the proper way to repair from this point on. And to some who didn’t want to feel like an a** by correcting others on technique I know I would have been very receptive to being taught the correct method. Thanks again!
