I'd just like to say that Sarge's putting meters transformed my game. Sarge was good enough to send me a meter for the Ghost many months ago. With it, and frankly due to it imo, I went from struggling Master to Legend.
Being able to feel confident with the speed of your putts is absolutely necessary to learning how to sink more curlers. I still don't get near enough to a lot of pins. But that no longer means I can't make birdie.
BEST addition to my game - and provided by a really good bloke to boot!
