A small, convenient and award-winning training device that helps golfers of all abilities improve their putting skills

AI GOLF’s The Gatekeeper is a small and elegant golf training device that helps golfers of all abilities improve their putting skills. Pendulum swing captures the mechanics of the putting stroke and addresses all key elements for success on the greens - face rotation, stroke path and tempo. Different ball sizes represent multiple difficulty levels and smart shaft connector allows to attach The Gatekeeper to any putter shaft type and size.

Having explored a series of concept mechanisms that mapped the mechanics of a typical putting stroke, it was ultimately the repeated testing of prototypes that allowed us to refine the function and precision of the final design solution.
