You’ve seen this concept used in video games, but now you can experience the power of “golf vision” on the real course.

The Golf Vision Green Analyzer is a revolutionary new product that will take strokes off your game and amaze your friends.

Golf Vision is the only product on the market that will provide you with a highly accurate, real time preview of your putt. The app analyzes slope and inclination data at specific points on the green to calculate the trajectory of the ball and where to aim. Golf Vision has a slope accuracy of 0.1 degrees.

The Golf Vision Green Analyzer is an invaluable training aid and stroke saver.

Our engineers scientifically designed the Golf Vision application to insure it’s accuracy.

*The Science*
The amount and angle of roll can be calculated from the ball's velocity, the angle of slope, and the friction of the putting surface. It turns out that the correct angle of offset or "aim" remains the same regardless of distance from the hole. For example, if the resulting angle of offset is 10 degrees at a distance of 5 ft, it will also be 10 degrees at a distance of 50ft.

*Methodology*
In a controlled environment, we carefully observed the roll of the ball on greens of different speeds. Specifically, data was recorded on greens with a stimpmeter rating between 7.5 and 11.5. From the data, we observed a relationship for ball trajectory and reversed engineered a formula which accounts for the forces on the ball resulting from friction and the angle of slope of the green. From this data, we are able to predict the roll of the ball for a putt with "perfect distance." Perfect distance is assumed to be the velocity that results in the ball coming to rest 2 ft past the hole. The application will draw two arcs, one showing the roll of the ball if it were
hit directly toward the hole and another arc displaying the angle of offset to aim. The application correctly accounts for differences in ball trajectory resulting from the speed of the green, break near the hole, and uphill and downhill slopes.

*How does it work?*
1) Set the speed of the green (very slow, slow, normal, fast, very fast)

2) Record Slope Data - Place the device on the ground in front of the ball and tap the screen. This will record specific data on the slope of the green (angle of slope and angle of inclination). Repeat this process at the hole and at any spot in between that you find necessary.

3) Move behind your putt, get both the ball and hole in view and take a picture with the app.

4) Press the "analyze" button and the app will compute the path of the ball
and the correct angle of offset to aim.

"I can't believe how accurate this thing is. A must buy for any golfer" (Jeff)

What's new in version 1.0.6
Calibration has been improved. When you calibrate, please make sure to first place the device on a flat surface. The calibration button will activate after 5 seconds.
