Abstract
Abstract A golf putting apparatus consists of a deck having an upper putting surface which deck is variably adjusted with respect to a base by means of several height adjustment devices, each comprising a bolt turnable by a handle and having a nut threaded thereon, which nut is held captive with respect to the deck so that turning of a respective handle effects a variance of the height of a portion of the deck and of the magnitude of the slope of the deck surface.
