The Sure Putt green reader is 2 inches around and a little less than ½ inch thick. It is made from high grade machined aluminum and electrically anodized for color. Because the color is part of the body, It will not fade or chip like paint. A precision state-of-the-art leveling vial is used to read the slope. The writing on the piece is machine engraved and not painted on. It is heavy enough to lie flat on the green to give a precise reading and small enough to fit comfortably in your pocket. Each Sure Putt comes with its own carry bag and is enclosed in a silver embossed box you’ll be proud to give as a gift.
