Abstract: A method and system for controlling the topography of a surface, such as a golf course green or fairway, through the use of a mechanical elevation control device placed below the surface of the earth. The mechanical elevation control device may be mechanical, pneumatic and hydraulic. Predetermined surface configurations, including historic configurations, may be stored in a memory associated with the system and used to configure a surface.
Abstract: A golf training device having a proximal stop a distal stop and a free moving weight.
