Abstract: A modular putting surface apparatus for creating an adjustable putting surface. Each module comprises a frame, a first and second end member, a center members and two surface members connecting the center member and the end members. The center member is adjustable up and down at each end to create a complex curved surface. Multiple independent support members allow the surface area to be sufficiently flexible so as to be adjustable and simultaneously rigid enough to support humans walking on the surface. Multiple modules are interconnected to for a larger putting surface. The entire surface area is covered with a cover material chosen for its putting characteristics so as to simulate putting on grass.
