It's actually mostly the golf ball. I don't think an Almost Golf ball would work. It might not even work if you put a silver sticker dot on it. It's not nearly as dense or solid as a golf ball, of course.
The club data except face and delivered loft are measured from the club, the ball data is all measured from the ball. It might not even think you hit anything and thus it might not even give you club data.
We have some AG balls. I'll try them out in the next week or so. I don't expect it to work.
I figured that the ball may not behave enough like a real one to get a reading. Thanks for the response.
