Golfers constantly face new challenges as they travel to different courses. Putting in nature creates many variables that need to be taken into consideration. The GreenPlay training system allows golfers to collect data from a putting green in order to more accurately shoot the ball. This small device sits on the ground and calculates the slope as well as the hole’s position in relation to the ball in an iOS/Android app. It’s a perfect way to train golfers into the right putting techniques, much like the X Ball, because it suggests the best way to putt. Early golfers can enjoy this system for $79 or $99 with a regular price of $250 by July 2014. GreenPlay needs to raise $50,000 in a 45-day Kickstarter campaign.
