◎About the Functions
GRAIN reader:
Just take a photo of the green from knee-height with your smartphone facing towards the cup, and GRAIN reader will give you a reading for both the roughness and direction of the grain. Your result is visually displayed with easy-to-understand arrows showing direction. The number of arrows indicates the roughness of the grain in 3 levels.

SLOPE reader:
Just place your smartphone on the green facing towards the cup and SLOPE reader will give you a reading for both the degree and direction of the slope. Your result is visually displayed with easy-to-understand arrows showing direction. The degree of slope is indicated up to 21 degrees, by number and color.

PUTT reader:
Use both GRAIN reader and SLOPE reader all at once! Just perform the necessary steps for using each function at a single spot on the green and PUTT reader will give you a simultaneous reading for both slope AND grain! PUTT reader can give you just the hint you need to help predict how the condition of the green will affect your putting.
