I’m in favor of anything that will speed up a round of golf. This looks like something that fits that bill. Have you ever watched a power cart player when he gets close to the green. He gets out of his cart, gets a club and then walks to his ball on the fringe. Then he decides that he’s got the wrong club and walks back to the cart. Then, after chipping, he walks back, puts the club away and gets his putter. Lots of time wasted.
The Caddy Mate is a detachable bag that carries all the player needs for the short game. Just detach the bag and head for the green. The thing’s even got spikes on the bottom so it stands up easily.
