A new player learns all about the target point and tangent line and ghost ball and aiming line to the pocket all at once. What can be better?
Although it is not for me I would think that every pool school and instructor should have one. Just think how many hours of trial and error practice at the table this will eliminate.
I know so many people around here who have absolutely no idea what the word tangent means let alone what a tangent line is. they are called APA players.
This should make a nice Christmas gift.
But of course, like any other electronic product, the price will come down.
Probably after Christmas.
