Bill McBride, I know there's some debate about Green Fix. Some, like USGA Green Section director Jim Snow, argue it's just another tool. But what I've seen and what some early studies suggest is that the GreenFix thing is easier to use properly and virtually impossible to use improperly in a way that would damage the turf. Conventional divot tools are extremely easy to use wrongly, and when used wrongly, they do more damage than if the ballmark had never been fixed at all.
