Used by many Tour Professionals and caddies to map out the greens, this device is one of the industry's best kept secrets.

In a compact size, with a leatherette carrying case, this tool reveals to the user a newer approach to putting. Simply place the device on the line of your putt to determine the break. It is accompanied with a user's manual and DVD to help you improve your game.

This device quantifies the slope of the green in 8 directions and from 0 to 9.9 degrees. You will be surprised how much compensation that you need for 1 degree of break versus 3 degrees at a distance of 6 feet. One of the most interesting concepts that the company recommends is to map out the greens with this device (as the tour caddies do) - This is something that even Stan Utley of the Art of Putting illustrates in his book.

Battery life is excellent. This device's battery has lasted me for over 1.5 years without replacing it.

This device is not for someone who does not have a consistent stroke. It won't putt for you. It won't teach you distance control. It will teach you how to read a green more effectively and make the most informed decision to stroke the putt.
