Sure Putt Golf Putting Aid The Sure Putt golf putting aid is a unique way to read the slope and break on a green. It can show any uphill, downhill, sloping right or sloping left break on any putting surface. The bubble in the spirit level will move around the dial to show you the direction of the break. If the bubble is directly in the center of the dial the green is level. But how often does that happen? By reading the dial around the disc you can instantly see the slope of the green. If the bubble moves right on the dial, that is the high side and the slope will be to the left. If the bubble moves left on the dial, then that is the high side and the slope will be to the right. Every quadrant on the dial shows you the path your ball will take on its way to the hole. The further outside the center circle on the dial the greater the slope or the greater the uphill or downhill break. To make it even easier the Sure Putt is large enough to have engraved directions in every quadrant on the dial and is heavy enough to lay flat on the green. giving you the most precise reading.
