Abstract
Abstract A practice golf net device utilizes a fabric-like member suspended from a frame to which are attached a plurality of shroud lines. The lines are connected to a mechanism which reflects the impact location of a practice golf ball contacting the net when hung downwardly, in a drape-like condition. The mechanism faithfully reports the angle that the ball takes relative to a line normal to the center of the net--emanating from the central regions of the net, as well as reporting the loft angle assumed by the ball. After each ball contacts the net, a release cord is manually operated by the player which resets the entire mechanism, readying same to provide a visual display of the distance that the next ball will travel, the angle it will assume relative to the target angle, and the loft imparted to the ball.
